Entei can be found in Leaf Green if your first Pokemon was Bulbasaur and you've beaten the Elite Four. Entei can be anywhere in the wild. There is no exact location.
You cannot capture miltank in leafgreen only Pokemon colosseum can.

You have to migrate it from Pokemon FireRed, LeafGreen, or any other Pokemon game that you happen to have an Entei in. Entei can't be caught in Pokemon Diamond or Pearl. Sorry.
