As someone who pushed ~4x the median PRs on my team before LLMs were a thing, I kind of think the problem here is PRs as a concept. Code review doesn't scale to prolific humans, it definitely can't scale to agents.
And the exact same things you would need to safely give up on PRs for human developers (auto-formatters, linters, comprehensive end-to-end tests, continuous deployment pipelines, etc), are also things that place meaningful guardrails on LLMs, and help them maintain a reasonable quality bar.
