Van Gaal has been linked with both the football director and manager jobs at Anfield.
Kuyt said: "He is a Dutchman, has a great track record and experience that the club could put to good use. (But) as a player, it is not usual to say what you think of candidates.
"At the moment, Liverpool have no coach or technical director. Each club benefits from structure. You look at the Dutch national team and see that consistency and clarity are important."
