You are right, systemd dropped support for static libudev (or any other
library for that matter) in version 205.[1] If you want to use systemd
provided libudev for lvm & c. in an initramfs, you'll need to include
the shared library and binaries linked to it.

I believe both dracut and genkernel-next support shared libudev, while
the current versions of genkernel do not (hence why genkernel is masked
on the */systemd profiles). While I have limited experience with
genkernel, dracut has dragged in all the shared libraries I have
required of it.
