Ugly yes, but not that expensive.  Depending on the list length testing
the additional not-ready variable can even be slower.

If you use CL macros, something can be done about the ugliness, though.
It could be written like this

(defun get-mode-line-struct (type)
  (dotimes (i (length mode-line-array))
    (when (equal type (mode-line-struct-type (aref mode-line-array i)))
      (return (aref mode-line-array i)))))


You're using a vector, probably because you're used to it.  Since you're
not doing random-access, a list would be more "natural" in lisp.

(defun get-mode-line-struct (type)
  (dolist (s mode-line-array)
    (when (equal type (mode-line-struct-type s))
      (return s))))
