Since I clean it so frequently I've begun to suspect the chainrings are wearing out the chain.
Could the acelerated chain wear be caused by the chain rings?

I think the answer to both of those questions is "no", but I'm open minded to learning otherwise.
Worn chain rings can indeed accelerate chain wear. So can using a chain checker accelerate perceived chain wear. Just use a ruler. A ruler is much more accurate than most chain checkers. Even with worn rings I would be extremely surprised if you were wearing out chains at 500 miles.
