You have the same problem that you have with legal LLMs; an LLM is incapable of providing legal or regulatory-involved advice, and anyone using an LLM for such purposes (even leaving aside hallucinations) forfeits any justifiable reliance defense. There's a role for LLMs, but no one with legal responsibility over reporting could or would possibly rely on an LLM for complex regulatory and rules analysis, not when there's the risk of your wardrobe being replaced with orange jumpsuits.
