I feel like you could get around the AI bit by asking about components and what they do, rationale for decisions, etc. If someone can't speak to it, it should be a clear tell.
It might be a more salient concern now, in the era of AI agents, and we are much warier today than I was at Matasano, but generally I think this risk is more talked about than experienced.
