Is there a way to fool the camera into thinking I have a longer lens mounted? I ask because that would result in a higher minimum shutter speed w/ "Auto ISO"
In other words, can I force it somehow to think it that my shorter lenses are all 135mm? I know that information is hiding somewhere.

Only by putting an adapter between the camera and the lens that would lie to the camera. The lens reports the current focal length, which is how zooms work.

Again, I suggest that you read your instruction manual. Learn how to use Manual mode, where you can set any shutter speed that you want.
Are you familiar with the “ Exposure Triangle “? If not, then Google it. You can set the camera to control all three legs of the exposure triangle, any two legs, any one leg, or no Automatic control, at all.

Hey, don't blame a guy for trying a workaround 😉 what would life be if you couldn't hack stuff?
Yes, I know how to expose things and I understand the exposure triangle. I'll play around more with manual mode. Most of the time I'm shooting at a fixed aperture w/ a prime, perhaps that will work.
When not, there's only one wheel control and three things to change. Any tips for button assignment? For example, I can see wanting to set
1) Auto ISO and auto exposure
2) Wheel assigned to control shutter speed
3) Button which, when pushed, will temporarily make wheel control aperture
I have only had the camera for a couple of days, it's very different from my d200; I'm still working on how to do this stuff.

"I have only had the camera (T7i) for a couple of days, it's very different from my d200"
You cannot compare these two cameras in the same sentence. They bare no semblance except they are both cameras. CCD vs CMOS for instance. 8 or 10 MP (I forget?) sensor vs a 24 MP sensor and on and on.
BTW, you can tape off certain contacts on the lens that tell the T7i what lens is attached. Try full manual mode and auto ISO.

Also, BTW, I do not recommend you do this. Just that it is possible. That is why I didn't mention which contact(s) to tape off.

Once again, my advice is to sit down and read the instruction manual. The T7i has a limited amount of button programming. There is a button on the back of the camera labeled as “Av”. That button allows you to use the Main Wheel to adjust aperture.
