The threatening nature of AI and even technology in general has always been a theme in science fiction because it's an easy and accurate prediction to make, as many of the themes tackled in the genre.
If anything, Japanese science fiction has way more and better pieces of media dealing with this, you are just ignoring it.
Some big and not niche animes that deal with technology or AI are GiTS, Akira, Lain and even Evangelion in it's own twisted way.
Most of the animes you listed are about wars mainly and robots are the weapons of the future, they don't directly deal with AI as a theme, but even then, when they do, they recognize it's threat.
AI and robots can be scary, but as most technology, it's inevitable. Pretending there is no danger makes favors to no one.
