LODing is something that you have to do yourself if you want that for meshes... ie make several meshes and swap them based on distance, size etc.
Terrains are generated from heightmap, so it's "easy" to LOD that runtime, but meshes are quite different. To this day I have not seen good "polygon reduction" algo even if it could use minutes or hours for the task; so it's quite impossible to do automatically during runtime.
