The thing about USB C dongles is that some contain their own DAC and others don’t.
The former is already universal so what you’re asking for exists but these are generally more expensive and the quality may not be as good as a pass through adapter if your phone has its own built-in.
On a different point about streaming to multiple devices, my phone (Realme) has a feature to use both the jack and Bluetooth headphones simultaneously which is great for the sharing use case without a splitter.
Would be great if it also supported multiple Bluetooth audio simultaneously.
