In general, I don't think you're going to find LT tires on anything less than a 3/4 ton truck. Even most 1/2 ton pickups come with P-metric tires, so I can't imagine any manufacturer putting them on a CUV.
Unless you're regularly taking your CUV onto the kind of off-road terrain where torn sidewalls and punctures are a big concern (and why would you do that with a CUV?), LTs are totally inappropriate and would be serious overkill, IMO.
