One does not dictate the other. You can use the zone read (as Kelly did with both Collaros and Lefevour), and still have a pass-predominant offense.
If your question is "Has Kelly ever used the zone read?", then I gave you the answers. And today's game shows you more of that with Zaire.
If you want examples of Kelly and a run-predominant offense, you would have to go back to his GVSU days. At that time, however, he was still using a spread offense, but with a rushing game that used traditional power runs from spread formations (i.e. he was not using zone read plays).
