No. It must be mounted in the initramfs or the kernel itself, usually

I think it does, but I haven't started developing lvm for BLFS yet.
What I will do though is to get lvm working as a non-rootfs system first
and then work on initramfs for use as a rootfs.
As a comment, I don't really think having the root file system on LVM is
useful. The really large systems are in places like /home or other
customized places. A simple 10G (a trivial size for today's drives)
partition will take all of / with ease. The larger partitions that may
need lvm can be mounted as a part of the booting process.
The only purpose of an initramfs is to mount the rootfs. Unless you
need to do a network mount for a diskless system, it is unnecessary.
All the big distros use an initramfs, but that's because they have a
'one size fits all' mentality. That's why we do LFS in the first place.
Sorry for the rant.
