What I tried to get through is that even if Ungoliant came from the Void, does that mean she's outside Eru's control?
Lalwende:

I think Bethberry is definitely on to something here, as the text clearly states that Ungoliant's origins are different to those of any other being. She is not Valar or Maia, as she did not come to Arda when they did, and she is not of Arda, as the text states she descended from the darkness. If Eru created Arda, then she cannot have been there already, as the Ents may have been. It seems she did come from the void, that place which is outside everything else. I like this, as it also tallies with my concept of her being something of a black hole in tangible, sentient form.

What I also like about this is that it allows for the possibility of other forms of existence outside Eru's control. Who knows which other enigmatic characters may have 'descended from the void'?!

What says that Eru didn't create the Void? And even if he didn't, things he created could dwell there. There was a time before Arda we can't forget. Arda is translated: The Realm and is according to Sil.

name of the Earth as the Kingdom of Manwe

Kingdom of Manwe, not Iluvatar. Arda is the creation of Eru through the song of Ainur. Eru doesn't lack control of everything outside Arda, Arda is a part of HIS realm.

But as Saucepan Man says, it's up to the reader. We don't know where Ungoliant came from, but the thought of her as equal of Eru seems farfetched. At least to me.
