In that case, a comment explaining this in 1-2 lines would probably be
fine.

Sounds reasonable to me.  Do add a phrase or two about this to the lc0
description though if it doesn't even ship a basic network.

In that case, for the description we should probably go with "Leela
Chess Zero" or "@acronym{lc0, Leela Chess Zero}"
