The most important feature of this narrative centers on subjectivity, but in order to know the intent of that subjective point of view, look at Leckie's treatment of gender in the novel. Leckie could have written a novel about male AI's and then switched it all to female at the last second, and it wouldn't matter to the story at all. So here's the central idea of the novel: Subjectivity is a bigger problem than just humans who can't get along. Subjectivity extends even to AI, rendering concepts like gender irrelevant. Because those ideas are constructed, in Leckie's view, the computers quickly outmode them, and just to twist the knife, they all choose female as the essential default.
This is a significant choice in terms of narrative, and although this represents an inversion of the expectations of a patriarchal society, the important thinker Joseph Campbell would likely call this completely natural, citing that for most of earth's history, human myths have been largely female-centric. This novel would belong to that preternatural point of view by returning the default to feminine instead of masculine.
This philosophical attitude goes all the way back to Plato, so notice how the main plot structure deals with justice. Not even the master of the Radch, Anaander Mianaai, can agree with herself, even though she's technically one computer with several different expressions. The problem of truth goes so deep that even a computer would likely reach a paradox that split it apart, or at least, that's the argument of the novel.
