You can combine the two expansions:
linecount=${#${(f)output}}

It's lines.
If you can replace the `find` command with a glob, it'll be simpler.
You'll also avoid quoting issues. If your code is supposed to handle
all sorts of file names, make sure it can handle files with backslash
and line feed in their names.
