In response to Regulus's conclusion:
I think LCL originated from Lilith, though I don't know if blood is the appropriate term. It clearly has some of the properties of blood (in particular the smell), but it's doesn't look like blood, and there is a whole sea of it there down in terminal dogma, so I don't think it is vital to keep Lilith "alive". Of course this begs the question of how Lilith exists without a soul (her soul is in Rei), but that's such a big topic I don't think it's a good idea to go into here (msg me if anyone wants to discuss it).
