You ask questions. Literally anything, like asking them why they believe this feature is needed, what their code does, why they made a DSL parser, etc.
The question itself doesn't matter. Just ask something. If their answer is genuine and making sense you deal with it like a normal PR. If their answer is LLM-generated too then block.
