Some functionality for creating legends for vectors is in d.vect.thematic.
However, I agree it is needed to abe able to display legends for vector layers
in a more convenient way. There was an attempt towards supporting vectors in
d.legend this by Jachym Cepicky some time ago,
http://les-ejk.cz/~jachym/programs/grass/d.legend.tgz. However, this is still
not fully operational. The latest news on this issue come from 01.11.2005:

Can anybody say what is the staus now?

It "only" requires somebody interested in developing the tool. However I'm
wondering how portable would be the pattern definitions which (I guess, I'm
not an ArcView user) are contained in avl? Anyway, importing color defintions
alone into GRASSRGB column could be possible I guess.

Some AVL examples:
