It's subtle, but volume 8 has it. Yen On's version, chapter 4, page 166.

"She vaguely sought someone to talk to. She created five small mechanical cubes. There were units for observation, analysis, validation, and adaptation, and a fifth to oversee and command them. It was her attempt at creating intelligence in this yet insensible world. Independent agents of reason, her wish for someone to talk to-someone to answer her infinite questions. But the mechanical wits-asked their own questions in turn. -What am I? What art thou? What is a question? The machines had intelligence but lacked something the girl possessed. Something she did not even know she had, because she was alone. For this reason, in the primordial world, that girl who was first to have a "heart" despaired."

When I read this, and I only finished the book a few days ago at this time, it made me ask myself, "Are they talking about the Ex Machina?" As they are machines built purely on logic, and lacked emotions. Which is why in Volume 6, and the No Game No Life Zero movie, Schwei is trying to comprehend the human heart. So I'm guessing this is the major bit that says she created them.
