Same with AI usage. If we allow people and companies to get away with “the AI did it; it wasn’t my fault” we are fucked. If you fail to supervise your tools (or the people you hire), you failed your job/duties and should be on the hook, unless there is clear malicious cheating by the other party (if you probably tried to do everything right and were cautious but the other side subverted that and acted in bad faith, then it’s a different matter).
