If a PR team was going to pick a fake reason to hide a blasé real reason, why would they pick the biggest scandal possible? I thought rich people tried to keep their personal lives out of the news. Saying that they had drifted apart naturally while the real reason was Epstein is something like what a PR counsel would do, that I could believe, but you're suggesting that they're making that trade in reverse.
Another point to bear in mind is that the legal team does not care what the public thinks because the public doesn't decide anything in court. Lawyers usually tell you to keep quiet about your case, to reduce the risk of saying anything in public that the other side can bring up in court to use against you. That's another thing that usually works backwards from how you're suggesting it is in this situation.
