I'd like to run a relay on my Umbrel if it's only using Tor. So far I haven't figured out how to route a connection from a non-Tor client to a Tor endpoint. Think clients will need to implement Tor in them for it to work properly.

I thought I saw a client that worked over Tor... Maybe I'm wrong, but I cannot remember which one it was.
You can run any web client in the tor browser. nos2x extension for firefox works in the tor browser too
