Right dircolors will set empty LS_COLORS due to not matching the TERM.
In that case ls will resort to using its default basic color set
(which it does because COLORTERM is set).

Adding various terminals to the default list seems not a general solution 
though.
I think we might handle this more generally by dircolors supporting
the COLORTERM env var which most terminals set, including alacritty.

As you say one can workaround this per user
on Fedora at least with:
printf '%s\n' TERM=alacritty 'INCLUDE /etc/DIR_COLORS.256color' >> ~/.dir_colors

BTW dircolors(1) should probably also have a mode to print LS_COLORS like:

  $ eval $(TERM=xterm dircolors)
  $ echo $LS_COLORS | tr : '\n' | sed 's/\(.*\)=\(.*\)/\x1b[\2m\1\t\2\x1b[0m/'
