automation relies on functions that take known parameters and reply with known responses. For complex functions, this requires writing logical checks, typically in the form of "if/then" statements. LLM (what marketing people refer to as AI) can take unknown inputs and return either known or unknown responses (depending on your prompt). This is very different from crafting "if/then" statements by hand. This allows machines to effectively learn and handle new inputs without a human having to write any code.
