Hi Brian-

No need to be concerned with protein levels for growing large breed puppies. 20 years of research has demonstrated that protein is a non factor in proper growth for LBPs.

Of the brands you listed off Fromm and Wellness are the 2 I would be most comfortable with. Other good brands to consider are NutriSource, Precise Holistic Complete, Purina Pro Plan, Hills Science Diet or Royal Canin. The last three have all gone through feeding trials on LBPs and are formulated by veterinary nutritionists who are keeping up to date with current research on the nutritional needs of growing LBPs.
