You are reading it wrong. That means:
util-linux needs to be built with USE="static-libs"
because
lvm2 is already built with USE="static"

None of which explains why you originally built lvm2 that way.

This has nothing to do with genkernel.
More than likely, you followed some daft advice on teh intarwebz saying
you need a static lvm to be able to boot / on lvm.
