so it sounds like the rear chain stays are asymmetrical from the factory.

That sounds like a bad idea. You are intentionally misaligning the frame now. A lot of classic frames cannot accommodate 28mm tires. That’s just the way there were designed. It makes no sense to misalign the frame to jam a 28mm tire in there.
