Ok I think I solved my own problem by accident and the solution is so simple that I feel embarrassed. If you select the static mesh and make it movable and select the dominant directional light and make it stationary it will not bake the shadows of the object and instead only give it dynamic lighting with LOD. I rebuilt my lighting added a skylight and it looks fantastic. With the foliage tool it still does the same thing dynamic shadows with no baked shadows. On a landscape you should probably use cascade shadow maps.
