Actually Mathematica is doing the stylistically correct thing here
because AB is a single name according to what you describe. In LaTeX,
authors sometimes get lazy and type names in math environments without
surrounding them by \text or similar things, but then LaTeX not only
sets them in italics but can get fooled into typesetting them the
wrong way because it doesn't know all characters belong to one name.

So you should in fact declare textual names as such. The best approach
depends a lot on what you're actually trying to do with your
expression in Mathematica itself (manipulate it algebraically, use it
as a label, etc.). To "emulate" the lazy italic LaTeX text, you could
mislead Mathematica with the same thing that fools LaTeX: TeXForm
[Subscript[p, A B]].

Of course if you actually meant for A and B to be separate variables,
then you might also want to consider using Subscript[p, A, B] to avoid
any ambiguities.
