FYI: You do not need this line if the file has an '.org' extension.

Note that this header applies to LaTeX and will not work with MathJax.
You can make Org to use actual LaTeX in HTML by adding
#+OPTIONS: tex:dvisvgm
to your document.

MathJax ignores \LaTeX but renders the function correctly.

MathJax does not recognize this, hence the "Misplaced &" error.
You have two options here: either (1) install the MathJax extension you
mentioned or (2) make Org to use LaTeX for HTML.
If you decide to go the MathJax/JavaScript route, please note that you need to
use Emacs 29 or later, where Org uses MathJax 3 and not 2.

MathJax does not recognize this either.

That happens because Org always uses LaTeX for PDF documents. If you want it to
use LaTeX for HTML too, see the OPTIONS above.
