It seems to solve a different usecase. LLVM is (by their own documentation) not really intended for ad-hoc JIT compilation for queries. It doesn't put a lot of priority on making the compilation fast (but rather makes the produced code fast).

On top of that, LLVM is a massive dependency.

I only looked at NativeJIT a few minutes but it seems to solve both of these issues. It's pretty small in terms of API surface // total amount of code and is explicitly designed for a usecase where compilation happens as part of a user-issued query (that needs to be fast).
