Base on what I have seen to far, Rizviem seem to have a complicated relationship with his own mother and evidence could be found when he named ophis other half power after her.

And to the other artifical super powerful devil, I am guessing that Hades used Lilith in a not yet reveal way to make them while at the sametime used somekind of trick to make them evolved to their grown up age. Like what happen to Vulcan from X-Men. I believe that this is what the original Lucifer was desperately looking for when he was making the original 72 pillars of hell.

But this is just a theory, I could be wrong.
