At the end of the day, LLM slop PR spammers are essentially adversarial actors. Git hooks are ultimately a tool for good faith developers within a given community (your team, your company, your regular contributors) in maintaining good hygiene and avoiding lapses into preventable mistakes. That's true for all CI, too.
And the truth is, too, that it's super easy for an LLM agent to run a build and tests. Good faith contributors using LLMs will never open PRs that don't build not because they're willing to "go the extra mile" and do manual work, but because they give the slightest fuck and have any respect or consideration for the humans they're working with.
LLM spam presents a different problem than any of that stuff was meant to solve. It's a malicious act, and you're right that tooling that burns the defender's compute can't be a solution. :-\
