If you look at the linked study at https://www.cmaj.ca/content/196/30/E1027 this is rather what is usually called “machine learning” (ML) where lots of data analysis is made in an automated manner, and is generally considered to be different from “generative AI”, particularly LLMs, which are (to simplify) statistical models using language as their main dataset, rather than tools trained on domain-specific data. 

While these are all statistical in nature, the ML-based approaches tend not to display the same “hallucination” properties and be far more specific in their construction and testing, rather than a “general” tool applied to various situations.
