yes, the OPA111 are unity gain stable. but thinking that if your PPA is in unity gain, then why not remove the Opamp gain stage completely, leaving only the diamond buffers?
there's no saying that the OPA111 isn't stable in unity gain in the datasheet, and there's some application circuit (also in the datasheet) showing the OPA111 working in unity gain, so guess it's stable.
