killall typically sends SIGTERM by default. It accepts a single argument, the signal to send - so shutdown would call it once with SIGTERM, then with SIGKILL. killall is not meant to to be called interactively - which worked fine, until people who had their first contact with UNIX like systems on Linux started getting access to traditional UNIX systems.

It used to be common to discourage new Linux users from using killall interactively for exactly that reason. Just checked, there’s even a warning about that in the killall manpage on Linux.
