Yup, I have been using this extensively. Paul's notes are something I forgot to mention-I referred to them almost daily, back when I was taking the equivalent of Calculus 1, and they're still very useful now that I'm taking differential equations.

Unfortunately, this doesn't quite work on OpenStax-I can't get LaTeX, all I can get is MathML, and that's not very easy to read. There's a way to navigate the math (using something called mathplayer), but it's quite inefficient as compared to LaTeX, specially as I go into higher math. The books are still very, very good, though.

Try playing with Mathjax's own accessibility settings. Not sure how well that works on Openstax, will work well if they're using Mathjax 3, badly otherwise.

Alternatively play with MathPlayer's settings (in the control panel), some of the other reading modes work better in certain contexts.

If you can, also try VoiceOver on the Mac, it has its own math support, which works pretty well.
