This will sound a bit odd, but I don't necessarily want to pay in a way that makes it look like I'm paying for the AI rather than the editor.

No, it's not odd, I like this take a lot. They almost need a dropdown menu indicating where you'd like your money to go to (editor, LSP, etc).

I'd also much rather have a means of paying a single flat fee to indicate my support than yet another subscription which is misleading because I have zero interest in the AI components of Zed.

Yeah, same here, the least interesting aspect for me.
