Not 100% I understand what you are trying to do here so here is what I think it is.
- You have a volume control FX block assigned to your expression pedal.
- You have set the Max volume for the expression pedal to 75%.
- The Volume control effect is toggled on and off using an assigned footswitch
- When you toggle the switch, the volume control is turned off and therefore the full volume of the amp is allowed to get through. You use this for solos
(Nice approach BTW).
What is not clear is which footswitch you are using .... one of FS1 - FS8 or the Expression Pedal footswitch.
If you are using FS1-FS8 then the red LED will be lit whenever the assigned effect is turned on. You cannot invert this logic (see below for an exception to this). This means that you cannot achieve what you want .... red LED lit when soloing
If you are using the Expression Pedal Toe switch then the LED flips between EXP1 and EXP2. If you want to use this then simply assign the volume control parameter and toggle to whichever EXP has the 'incorrect' LED assigned. That way, when you flip the switch, the volume control gets turned off and the 'correct' LED gets lit.
Finally, a workaround for FS1-8. Remember you can assign multiple effects to a single footswitch. If you are willing to sacrifice an effect block then you could use a 'neutral' effect (e.g. Studio EQ with all parameters left at default) and assign this to the footswitch first. Make sure that the effect is toggled off with the footswitch then assign your volume control to it, switched on.
Now, the LED will track the state of the first assigned effect - the Studio EQ - which should be turned off when the Volume Control is turned on. Therefore your LED will be lit when the volume control is turned off and be lit when you are in solo mode.

The issue with the switch LED being on or off has confused me on stage before, because sometimes a solo boost involves turning something off first and then turning something on, which makes the "off" stage actually look "on". Hadn't really thought of placing something neutral first just to force the switch LED state. Very nice, thank you!

Yes, that is true ... and what I generally do also. It costs you an effects block but it is very controllable (and led-state friendly )! I use a simple Studio EQ boost or alternatively a mid EQ when I want to wail or cut more.
I like JLEpperson's basic idea though of assigning a volume pedal block with max 75% and then clicking the Expression pedal toeswitch to 'release' the volume up to max desired for soloing. Another option for the toolkit, where needed.

For a clean boost: a studio EQ is ideal. If you just boost the gain parameter then the boost is tonally neutral. It seems to have a decent amount of headroom and plenty of gain on tap. Be careful not to clip the input of the amp/desk/computer that you are plugging into.

Just wanted to expand a little on Jim's good comments based on my own experience with the stuido EQ ...
The Studio EQ is neutral, for the most part at least! I think it is completely neutral only if your input signal level to the Studio EQ is less than about -9dB at 0dB or negative gain settings. In many use cases you may have a higher input level if the Studio EQ is placed after the amp or mixer.
After running into distortion problems I checked a whole set of data points via USB and a DAW and found that just placing the Studio EQ into the signal path lowers the output signal by an increasing amount (up to about 2dB) even when its gain knob is left at 0dB if your input level is above -9dB. Also watch out for incorrect dial knob value to output level translation. What you dial in may be up to -2dB off from what you'd expect to get even if you output is less than -9dB.
Within this 'margin of error' your dialed in gain only does what you expect if the adjusted output level is below -9dB. If your gain setting tries to push the output higher the studio EQ starts to 'soft clip' (initially very little) and gives you even less output level than you'd expect from the gain setting (and factoring in the error margin). Depending on where you started and how much gain you dial in you can get quite nasty sounding ouput distortion. Note, it does all that well below 0dB, the reall digital clipping point.
I believe the Studio EQ behaves like this because Line 6's model imitates the real API 550b, which has a soft clipping feature and 12 or more dB headroom, i.e., you'd need do start this 'feature' imitation that many dB below 0dBFS as there simply is no way to do 'soft clipping' above 0dBFS. My guess that 'feature' kicks in at right about -10 to -9 dB input level.
Hope this helps some Studo EQ users. I'd guess most of us have run into some unexplained distortion with it. I can post my data in tables should anyone be interrested in the details. Let me know (and give me a couple days ;-).

Most of the time I use a Boost Comp, with compression set to zero, a little drive (20%) and I play with the output.
Depending on what I want to get, I'll play with the Bass or Treble knob, to add a little bit of this or that.
