There is no universal option to produce the same errors with TeX4ht,
as it would require no changes to the LaTeX code. We use these changes
to insert HTML tags, so without them, the conversion wouldn't work.

In this particular case, you can use the no_ and no^ options. They
disable TeX4ht redefinitions of _ and ^ characters. This causes
problems with math in TeX4ht, but as you use MathJax, it shouldn't
matter for you. So try this:

$ make4ht  -ulm default -a warning index.tex "mathjax,htm,no_,no^"
