There are offset flanges available. They are usually 2" and, I think,
were designed to adapt 14" (wall to waste pipe) toilets to 12" and vice

deliberately put in a place so that the door would clear when opening
inward. I changed the door to a pocket door and re-did the cabinets.

You mean they didn't just cut a hunk off the bottom of the door so it
would clear the toilet?

Yes, in my years of working as a plumber, I saw this several times!
