The answers to most of the questions you asked are in the ebuild file
and in the ChangeLog. You can find them at

$PORTDIR/sys-fs/lvm2/



amd64, elibc_glibc, kernel_linux, multilib & userland_GNU are not in
emerge output as those are not USE flags in the regular sense of the
word. Don't worry about them, they define the basic settings upon which
portage built your host. Change any of them only at your peril, you will
break things horribly (and keep N pieces, where N is a big number). You
can see the full lot near the end of

emerge --info
