Indeed, edge pawn + bishop of wrong color is theoretical draw, if the defending King can get in front of the pawn.

Yes
It is a known draw and I used this idea of draw in tournament games even in the time that I had a rating near 1600.
The endgame is a draw even earlier after 168 moves when olithink had KBPP vs KB based on tablebases.
Olithink could win by
164.g5 or 164.Kc5

I used to pull my hair out trying to run the king out of the corner with the wrong colored bishop, until i realized.........
