There is an ALT tag with the original LaTeX code.  Can you elaborate on
what is missing and how this could be improved?

I tested the page https://mathjax.github.io/MathJax-demos-web/tex-chtml.html
with lynx (there are no Texinfo manuals with mathjax enabled I know of,
if anybody knows about one, please tell me), and the result seems good
to me, the LaTeX code is shown which is not a bad choice for math in
a terminal.

For one example of a texinfo doc using Mathjax, see https://maxima.common-lisp.dev/.  In particular, you can look at https://maxima.common-lisp.dev/docs/maxima_79.html.  A maxima user (who might be blind?) says that the MathJax-enabled formulas work really well with a screen reader.  Mathjax appears to support accessibility well.

I don't have lynx and actually have no interest in using a text-only browser.
