root should be /boot, not /boot/efi, since it is where you have vmlinuz-xxx

initrd /initrd.img-5.5.3 should be on a line by itself, not on the "linux" line
the root= parameter should point to the filesystem you want linux to use as /,
that is /dev/mapper/lfslvm3-root
so if you want to use an UUID, it is 9c82c592-859c-4333-b09e-b0485ad72b3c

the line above should be OK, except you need to remove the initrd=...

Maybe, at the point you are, you could try to read more general
documentations, about lvm2, grub, uefi, etc. That's how we make documentation
for lfs...
