Maybe maybe not.
But that doesn’t change or address that Mary did not *ASK* Him anything. She TOLD Him a fact.
When I was a very young child, my Mom would sometimes tell me, “It’s past your bedtime, Ebb”.
She was stating a fact. She wasn’t directly asking me a question or giving me an order.
But I understand what she meant, and I went to bed.
Secondly, if Mary was not expecting a postive reaction from Her Son, why did She then turn to stewards tell them to do whatever Christ told them to do?
So you don't believe Jesus Christ, the Second Person of the Holy Trinity, was omniscient?
Wow!
