He saw only two options: either the succession of compelled motions preceded our current state for ever, which would lead to an infinite regress and, thus, irrationality, or there must have existed, at some point, an "unmoved mover." The argument, even in its most modern iteration, rarely mentions "God." The argument was never meant to demonstrate the identity of any particular entity, but rather to demonstrate the intelligibility of the universe.
But again, the major difference now is that the scientific data suggests the universe did, in fact, begin to exist; thus, there is no way for the assumption to be considered a fallacy in the manner Russell was suggesting in the early 20th Century. Surely, you can understand this.
You must forgive me for doubting your interpretation of Kant. Because first cause/cosmological arguments rarely mention God, and ontological arguments explicitly mention Him always, I find it dubious that Kant would ever suggest interchangeability unless he was referring to the wording of one cosmological argument in particular. Additionally, I find it unlikely that Kant would suggest that the ontological argument for God involved an "a priori assumption of God's existence," which would make it a clear and obvious instance of question begging that would have escaped notice for centuries. I also find it unlikely because the ontological argument assumes not that God exists, but that one can conceive of Him irrespective of His existence. So at best you have excluded the majority of Kant's logical burden or, at worst, grossly misinterpreted him. Because you present Kant's objection to the ontological argument without really demonstrating a grasp of his reasoning, it ends up looking an awful lot like an argument from authority.
And just as a fun question: if we know all of a car's constituent parts began to exist, is it a fallacy of composition to assume that the car, itself, began to exist?
