No-coverage answer
There is no information in the Taygetan contact material to answer this question. Lilith — described in various traditions as Adam's first wife, a demon, or a figure of feminine rebellion — is never mentioned in any transcript. While the material extensively reinterprets the Genesis narrative (identifying Adam and Eve as enslaved Lyrian races, the serpent as Taygetan women, and the Garden of Eden as the Atlantis stronghold), Lilith does not appear in this reinterpretation. The transcripts do not address whether there is any historical or extraterrestrial basis for the Lilith figure.
