The first LZ-step pretty much directly maps to BPE tokenization in LLMs.

If doesn't correspond cleanly. I can see why you draw the link, because LZ compression will replace words with symbols but BPE is a non-contextual entropy encoding while LZ is contextual and adaptive and that makes it very different. I think BPE actually has more in common with Huffman encoding.
