I can imagine that if we ever reach a point where the interviewers are prepped with the useless corporate answers to these reversed interview questions, it means we’ve done a great job in pushing to get the right information and gets right to the crux of their issues and possible red flags, one of which might even be a “corporate culture cover up stock answer”. Then surely just a follow up question asking “is that also you personal experience here?” And if you still get a corporate answer then you know for certain it is a red flag. Ultimately it sounds like these sort of questions could work well.
