I would prefer not to use `add-hook' nor the `lambda'
notation but in essence a non-interactive function
that prompts for input vs. an interactive function
that is called interactively from Elisp code - that
should amount to the same what I can see.

If you want the function to be used interactively *as
well* (i.e., the user invokes it directly) then
obviously it should be interactive.

Or perhaps you are benefited from the
`interactive' interface.

From a principal/esthetic point of view interactive
stuff doesn't really belong in hooks because those are
all about automatization. But in reality if that is
what you want and it works - why not?

Try it:

(require 'message)

(defun spell-before-send (lang-input)
  (interactive "sLanguage [e or s]: ")
  (let((lang (pcase lang-input
                ("e" "american-insane")
                ("s" "svenska") )))
    (when lang
      (ispell-change-dictionary lang)
      (ispell-message) )))

;; (setq message-send-hook nil)
(defun message-send-hook-f ()
  (call-interactively #'spell-before-send) )
(setq message-send-hook #'message-send-hook-f)
