Curiously, I’ve been scratching this itch just today. So I might as well
share.

I presume you are using some of the specific values of
`org-refile-use-outline-path'. If that’s the case, the file level as a
refile target is hardcoded in `org-refile-get-targets', independently of
what you might have in `org-refile-target-verify-function'.

We have somewhere in `org-refile-get-targets':

#+begin_src emacs-lisp
(when (eq org-refile-use-outline-path 'file)
  (push (list (file-name-nondirectory f) f nil nil) tgs))
(when (eq org-refile-use-outline-path 'buffer-name)
  (push (list (buffer-name (buffer-base-buffer)) f nil nil) tgs))
(when (eq org-refile-use-outline-path 'full-file-path)
  (push (list (file-truename (buffer-file-name (buffer-base-buffer))) f nil nil) tgs))
#+end_src

(`tgs' is the local variable which is collecting candidates for return).

So, you might not use `org-refile-use-outline-path'. In this case the
file info will be provided in the end of the refile target in
parentheses (for targets outside the current buffer). And the file level
will not be offered as a target.

I, however like `org-refile-use-outline-path' and set it to 'file. But I
also want to not be able to refile to the file level. So I advised
`org-refile-get-targets' with:

#+begin_src emacs-lisp
(defun my/org-refile-filter-targets (orig-fun &rest args)
  (let ((targets (apply orig-fun args))
        (agenda-files (mapcar #'file-name-nondirectory org-agenda-files)))
    (cl-remove-if (lambda (x)
                    (member (car x) agenda-files))
                  targets)))
(advice-add 'org-refile-get-targets :around #'my/org-refile-filter-targets)
#+end_src

This presumes (setq org-refile-use-outline-path 'file). If you use any
other value, you should probably adjust the function’s let bound
variables for the case. This is also sort of hackish, so exert your own
due caution in choosing whether or not to use it.

HTH,
Gustavo.
