Emerge can cope quite happily with "emerge libreoffice", and also with "emerge libreoffice-bin". So if somebody packaged an lsb version, and a gentoo maintainer created a "libreoffice-lsb" package, then fine.
I would just use the syntax I've always used, "emerge libreoffice-lsb", and let the emerge magic look after actually getting the package onto my system.
THAT is the way lsb is supposed to work - the lsb format is actually a restricted set of rpm, that is known to work well with alien, so that distros that want a .deb can easily convert it and install it. So that debian/ubuntu/mint/whatever users don't have to learn rpm/yum/yast/whatever.
