I think you're conflating "knowledge" with "intelligence". And, "agency" seems to be a missing concept, which is the only way for something intelligent to apply its knowledge to achieve something practical, on its own.

Google search can't achieve anything practical, because it has no agency. It has no agency partly because it doesn't have the required intelligence to do anything on its own, other than display results for something else, that does have agency, to use.

The applicable definitions, from the dictionary:

Knowledge: facts, information, and skills acquired through experience or education; the theoretical or practical understanding of a subject.

Intelligence: the ability to acquire and apply knowledge and skills.

Agency: the ability to make decisions and act independently.
