How do I keep my craft when I use AI animation tools?

You use AI tools now, and they help, but the line has blurred, and you are no longer sure where your craft ends and the machine's generation begins. That uncertainty is honest, and it matters, because your craft is your identity, and you do not want to lose track of it inside the tool. A helpful way to see it, the tool can generate, but you are the one who decides, what is good, what serves the story, what to keep and what to throw out. Your craft is not only in making each frame by hand. It is in the taste and judgment that shape the result. The generation is raw material. What you do with it is still you. Stay deliberate about the choices. Use the tool to move faster, but keep making the real decisions yourself rather than accepting what it hands you. Ask of each output whether it is actually good or just convenient. As long as your judgment leads, the craft is still yours, no matter how much the tool speeds up the making.
