This can usually be solved by coaching, not only for this person, but for the teammates who are spending more time answering questions.

For coaching the questioner, I ask them how they approach finding information, and recommend they time box their exploration, and only ask their question if they've given it a good try. I I also will describe my personal workflow to find answers when answering their questions.

For coaching the rest of the team, I often suggest they ask "what have you tried so far?" or "where have you looked so far?" before just giving an answer. This can help show knowledge gaps, and oftentimes the questioner will take another look and discover the answer themselves.

And yes, if they never get away from this behavior even after getting feedback multiple times, then that turns into a different sort of conversation.
