It used to be broken, but with the c-u-f merge the 'tlmgr' tool now
works as expected to search for things in the local texlive.tlpdb
database:

--8<---------------cut here---------------start------------->8---
$ guix shell --pure texlive-bin grep which coreutils sed gnupg -- tlmgr info cite.sty
tlmgr: cannot find package cite.sty, searching for other matches:

It's not great that references to 'grep which coreutils sed gnupg'
aren't patched though (I thought I cared they were, perhaps it
regressed).
