Actually, as Amara pointed out, he created them to have lesser beings to make him greater, as he was equal to her. I think the necessity of having them imprisoning her only came later. And, well, for Lucifer to know her well, he need to have spent time with her. Lucifer is the second, which means that Michael already existed, and nothing goes against the theory both Raphael and Gabriel existed too, which is also supported by the fact all the four are alive to battle and lock her. Also, God said it took time to create them. He never said how long it would take, but I would say that the timespan between Michael's creation and Gabriel's own was sufficient for her to accept, at least, Lucifer. This would mean that, given enough time, she would be fully accepting God's creations and there would be no need for locking her away, although the difference between accepting a single being and accepting an entire universe could took a long time from her
