I have a small theory establishing a relation between the Titans and the ToL.
I would definitely attribute the Titans to Binah, or at least the first . Since they all come from Gaia, I could easily identify her with the "mother of abominations". For instance, Selene, as the Lunar role of Binah in the Heavenly Hexagram; Oceanus, the ocean, which is quite clear related to the great waters of Binah - and his sister/consort Tethys, also a Titan, holdiing similar attributes; Cronus/Saturn as the planet; Eos/Helios/Hyperion as the Saturn-Sun (I really can't recall from which mythology or age that was, but I'm pretty sure Saturn was considered as the first sun or father sun, or something like that).
As for their children, the Olympian Gods.. I think I would relate the Titanomachy to the breaking of the Logos at the abyss. Since the expansion of the Sephira is taking place downwards (f.i. the sword), I would consider the part of the mythology after the Titans have been defeated as a reference to the world from its current perspective, below the abyss.
