The usually way of handling this is to add a function that
interprets its arguments and can tweak them before passing
them through.  The tricky bit here is that git can take
options which you need to be able to take account of, so
the obvious trivial

git() {
   case $1 in
   (rebase)
   set -- rebase --keep-empty "${(@)argv[2,-1]}"
   ;;
   esac
   command git "$@"
}

isn't good enough.  But it's a start.

I haven't tried myself, but presumably you tried

   git config --global alias.rebase "rebase --keep-empty"

and that didn't work?
