Odd statement, as it is of course always the thinker that gets the attribution, i.e. the manipulator of tools and the interpreter of results.

E.g.1: Galileo saw Jupiter, not The telescope saw Jupiter.

E.g.2: Joe built the wall, not The crane built the wall.

In this case, AI is the thinker, not a human, hence the phrasing.

A human creating the AI does not remove the attribution either, just as we never say Joe's mother built the wall just because Joe was created by his mother.
