Sure, manually written API docs are a thing of the past. But this has been true even before the era of LLMs. But I'm not that sure that this argument stands for all kinds of software. Depending on the abstraction between your source code and the things your users want to achieve, the expert view of a technical communicator might be necessary in order to come up with instructions (how-to) that meet the needs of the person seeking help instead of just summarizing the software code in natural language.
