The madness tables in the DMG explicitly list a 'attack the nearest creature' option. So there's that.
There are no general AL rules against PvP. (If you think there are, please cite them.) The rule is against 'undermining' other characters, and I totally understood why that rule exists when I was hiding from a raging barbarian while two black puddings were threatening to devour the rest of the party.
The point is that this wasn't a situation in which the DM could say, 'no, you're not a megalomaniac, that's not a valid option in this campaign'. The option was explicitly provided in an AL adventure, so the DM was not comfortable overriding it, as that would suggest that the DM could also override things like 'Trapped in the Mists' or other AL content that restricts or informs player options.

Actually there are rules against PvP in AL. AL Player's Guide
p4
"No Undermining of Other Characters During
Adventures. Adventurers are brought together by
common cause, and during an adventure, they’re
expected to work together to overcome challenges.
Though certain factions might find others distasteful,
individuals will put that aside and become a team when
put in dangerous situations. In short, play nice with
each other when things get deadly."
also code of conduct p9
"Participants must not conduct themselves in a manner
that is disruptive to the enjoyment or safety of others
at the event."

I don't think the problem in this situation was AL - it was the players, the DM, and the shop (in my view).
