Well, I don't know of any tools that can extract the models from the .lsz, but JPCSP has a feature that allows you to rip the models and textures that are on screen like 3D Ripper DX and printscreen can do.

When your playing the game with JPCSP, you can goto "File>Export 3D scene (Wavefront .obj/.mtl)". It will dump everything to a folder called
"export".
