Sounds like they don’t even need to pay for AI. Maybe a deterministic script that does some basic quality checks like verifying that the linked repository isn’t day old slop, and auto-rejects the ones that don’t pass muster would be better. For starters, then you could have well-established and documented rules. Which people generally seem to prefer over AI referees that reject things for opaque and confusing reasons (e.g., YouTube moderation) and can’t be reasoned with.
