The LLVM dependency is in the HW-specific driver solib which is loaded by the OpenGL library, which has the same soname as before.
The author states this is an llvm16 issue, but unless the driver was built against llvm16, it should still be loading llvm15.
If it was built against llvm16 (or loads llvm16), and doesn't work, that's not a failure of anything other than QA testing.
