AI has been a thing for decades. It means artificial intelligence, it does not mean that it's a large language model. A specially designed system that operates based on predefined choices or operations, is still AI even if it's not a neural network and looks like classical programming. The computer enemies in games are AI, they mimick an intelligent player artificially. The computer opponent in pong is also AI.

Now if we want to talk about how stupid it is to use a predictive algorithm to run your markets when it really only knows about previous events and can never truly extrapolate new data points and trends into actionable trades then we could be here for hours. Just know it's not an LLM and there are different categories for AI which an LLM is it's own category.
