IMO i think she could possibly be related to trihexa, but not in the way you might think. given how rizevim is a pureblood devil we can assume so was lilith. but according to some myths she was originally human. so how could she have been turned into a devil? given how much rizevim knew about trihexa, it would stand to reason that he aquired his knowledge from him his father, the original lucifer, who was around prior to the beast being sealed, which explains how rizevim knew how to unseal it. if the beast is the imbodiement of all evil then perhaps it was the one to tempt lucifer to rebel against god.

Now how does the relate to lilith? think back to what happened to isse in v12; he was remade in the flesh of GR. given the current state of lilith's body, it could stand to reason that she was remade from flesh aquired from.... trihexa. this would perfectly explain why she is in her current condition, why she is such a valuable asset, and why the original lucifers descendants are so much stronger then him. this also set's up a future power up for vali as previously mentioned on top of serving as a basis for a way to defeat trihexa in the future.
