Personally, "this monster is abnormally susceptible to toxins" seems like a perfectly valid justification for a weakness to poison damage (after all, we're already operating at the level of abstraction where all toxins deal the same 'poison' damage) but at the same time, I don't think weakness to poison would ever be a broad enough category to excite poison users. It strikes me as a much more niche thing that would have to be on a case-by-case basis rather than 'these types of monster burn more easily, these general traits make you weak being frozen'.
Traditionally, divine beings were quite weak to poison (probably as a metaphor for human treachery) though that's definitely still going to run into the issue that they're going to be relatively few in a traditional campaign, even if we include things like 'mythological godspawn that aren't holy-coded in D&D' like centaurs in the list.
