They seem to use various sources, so it is difficult to be sure. The 110 black & white film has been suggested as being an Orwo emulsion, because of the developing times. That seems a possibility as Filmotec make black & white 16mm cine films. With the new "Purple" Lomochrome film (a C41 film in 35mm & 120) their website says it is being made in a new production facility. That could, I suppose, mean new to them. Interestingly the BBC report that the Lomography company are one of those believed to be interested in Kodak's film facilities. No doubt we shall eventually learn the truth.
