There seems to be no other way than to modify `gnus-topic-topology'
(~/.newsrc.eld specifies its value).  How about this?

--8<---------------cut here---------------start------------->8---
(require 'gnus-topic)

(add-hook
 'gnus-setup-news-hook
 (lambda ()
   ;; Create the "utn" topic if needed.
   (unless (member "utn" (gnus-topic-list))
     (gnus-topic-create-topic "utn" (caar gnus-topic-topology)))
   ;; Add `(subscribe . "\\.utn")' parameter to the "utn" topic if needed.
   (let* ((subscribe '((subscribe . "\\.utn")))
	  (topology (cadr (gnus-topic-find-topology "utn")))
	  (len (length topology))
	  (params (car (nthcdr 3 topology))))
     (cond ((= len 1)
	    (setcdr topology `(visible nil ,subscribe)))
	   ((= len 2)
	    (setcdr (cdr topology) `(nil ,subscribe)))
	   ((or (= len 3) (equal params '(nil)) (not (consp params)))
	    (setcdr (cddr topology) `(,subscribe)))
	   ((not (assq 'subscribe params))
	    (setcdr params (copy-sequence params))
	    (setcar params subscribe))))))

If you want to set the group level, try adding this one:

--8<---------------cut here---------------start------------->8---
(add-hook
 'gnus-setup-news-hook
 (lambda ()
   ;; Add `(subscribe-level . 1)' parameter to the "utn" topic if needed.
   (let ((params (car (nthcdr 3 (cadr (gnus-topic-find-topology "utn"))))))
     (unless (assq 'subscribe-level params)
       (setcdr params (copy-sequence params))
       (setcar params '(subscribe-level . 1)))
     params))
 'append)
