Yes, we have Shedskin in the list at the bottom of https://lpython.org/. Note that the Shedskin compiler is written in Python, so the speed of compilation might be lower than other Python compilers written in C++. Unless it compiles itself, that would be interesting. We thought about eventually writing LPython in LPython, but for now we are focusing on delivering, so we are sticking to C++.

Can LPython transpile existing Python type inference libraries written in Python to C++?
Only if the libraries used the subset of Python that LPython can compile. So currently no.
