This confuses two things still:
People wanting to have natural language to machine code via AI, just AI that was implemented the way they thought was achievable then (symbolic AI).
People wanting to have natural language style programming language, similar to later AppleScript or some 4GL languages.
Natural language programming, or natural language processing, as it was called, was tied to the first, and the AI research of the time, from the beginning:

So, yeah, they didn't have LLMs, but they pretty much understood such a program or "compiler" would need to understand world facts and natural language to even work.
