On face value separate accounts sounds like a good idea. In reality, unless you make separate accounts for each bill you pay it wouldn’t be practical to cut off every company you pay bills to in order to protect yourself against one. You would be eaten alive by bank charges if they even allowed it in the first place.

My bank was bought out by a larger bank. I had to go to every entity I do net payments to, and change all my account info. Iy was a PITA!

Not really. It's obviously not the best option, but it protects what's in your main accounts at least. And, you should be able to tell your bank not to honor any fund requests from certain companies. I try to set up bill-paying as push instead of pull as much as possible.
