I don't think it's likely that software developers can be sued on the grounds of "some people use it for illegal activity". Can IP rights holders sue any torrent tracker on that basis? Not to mention that playing backups of your own games is explicitly legal in many places, and I'd be shocked if it isn't in the US. Lastly, one can make an argument that the purpose of Yuzu isn't playing "Switch games", but emulating the Switch hardware stack, which is legal. For example, writing your own Switch homebrew and running it on Yuzu is permitted.
