The 23.0 profile uses merged /usr as its default. You can, however, remain
with a split /usr for now. What you can't do is mix the two.

I run a merged /usr profile 23.0, and my libclang.so.17.0.6 is bigger:
# ls -la /usr/lib/llvm/17/lib64/libclang.so.17.0.6
-rwxr-xr-x 1 root root 32579024 Jun 2 12:15 /usr/lib/llvm/17/lib64/
libclang.so.17.0.6
Have you re-emerged your toolchain and in particular sys-libs/glibc?
