[O] Escaping an underscore in LaTeX export

LaTeX recommends \_ as an "escaped" underscore. In other words,
"really use the underscore, not a subscript." When I do this in
Org-mode and export via =C-e l p=, I don't get that behavior.

Here's my options header:

#+OPTIONS: *:t TeX:t LaTeX:t

a\_b  -> a$\backslash$$_{\text{b}}$
a$\_$b  ->  a\$\_\$b
a $\_$ b  ->  a $\_$ b

What *does* work, is this:

a\(\_\)b  ->  a\_b

If this is the best/only way, that's okay. However, if others believe
that it should be passed through as \_ to LaTeX, perhaps that's the
best way? After all, just passing along _ works to subscript whenever
and wherever with my tex:t and latex:t options... perhaps escaping it
should also work?

An analog might be the use of \$, which escapes the dollar sign and
passes it through to appear as a dollar sign in the final document. I
suppose I'd make the case that if that's interpreted to be escaping
(vs. converting it to $\backslash$$), then perhaps escaping an
underscore should be treated the same.

Fringe use that I just stumbled on and isn't a critical issue, but I
thought I'd mention it.
