Yes, and by far the most important aspect of the trailer application is that buyers want an exceptionally cheap tire, with adequate load capacity in a small size. This is why the 3500 pound capacity axle on an Escape is carried by two tires which are smaller than anything you'll find on a car with much lower axle capacity.
LT and commercial tires are for driven and non-driven positions on severe-service vehicles, including trailers. ST tires are not appropriate for anything other than trailers, but of course that's not a problem when using them as intended.

Typically people chose LT tires for trailers...
- to get sizes that they cannot get in ST,
- to get load capacity they could not get in ST (but higher load ranges have become available in ST tires),
- to get a higher speed rating than they can get in ST (but ST speed ratings are going up so that's less of a concern),
- to get better-quality tires than available in ST,
- to match the tow vehicle tires so they can use the same spare tires and even other components (which is common in Australia, but not here), and
- for appearance (such as a "rugged" look on "off-road" styled trailers).

No, LT tires are generally sized for recent light trucks, and light trucks haven't used 75-series tires for 15-inch wheels in many years. There are some sizes which would work in overall diameter and width, but would need 16-inch wheels... which are hard to find to match the trailer hubs.
