Maya LT is made for mobile game development primarily, it has pretty severe limitations on polycount in the scene that limit what you can do with a highpoly bake for targeting PC or console spec. As far as I’m aware, it also has some limitations on what formats you can export as for working in other programs, and also doesn’t have support for third party plugins like the Nvidia PhysX plugin you need to make any cloth/physx effects in Unreal. It also doesn’t include any of their dynamics functions, so you won’t be able to make your own particles or export the vector fields for gpu particles.
Maya LT is by design, very limited. You get their modeling toolset, the basics of their rigging tools, and their animation tools, and that’s it, nothing else.
