There is only one file type that uses the .LLM extension:
Linden Lab Mesh File
Linden Lab Mesh (LLM) file used by Second Life, a network-based virtual reality world; contains a 3D "mesh" definition as a collection of polygons that form the surface of an avatar; used to render a 3D avatar and create texture wrappings.
LLM files are created in one of two mesh definition formats, base format or level of detail (LOD) format. Base meshes contain the original mesh definition, and LOD meshes contain alternate meshes in a decreasing resolution that are used when the avatar is far from the camera.
LLM files are also called Linden Binary Mesh files.
