Indeed, so

--8<---------------cut here---------------start------------->8---
(defun th-repeat-last-shell-command ()
  (interactive)
  (if (car shell-command-history)
      (apply #'shell-command (car shell-command-history))
    (message "There's no last shell command!")))
--8<---------------cut here---------------end--------------->8---

is enough.
