Actually, this seems to be the default when extracting as root. At least
my tar insists on giving the extracted files the uid of the creator
(unfortunately this is often not root).
Furthermore --owner and --group seem to have no effect when extracting so
when extracting as root there seems to be no way to prevent files from
being assigned to a non-root account :-(

No. The files will be owned by a user id without an account.

That is the only solution I see. This is why I suggested to add
chmod go-x $LFS
to the book as a security measure. This will protect everything that
happens on the $LFS partition and once LFS is finished there should remain
no non-root-owned files.
Join the Army, meet interesting people, kill them.
