How? I'd expect them to already have standardized lists of the most useful next thing to investigate given what's already known, and a modern "AI" would actually be worse at that than some sort of solver engine with a database of costs/risks (for tests) and conditional probabilities.

Maybe if they're still using (digitized versions of) paper flowcharts things could be improved, but the most powerful tech should be old-school stuff rather than modern "AI".
