The thing with Trinity Force is that every AD champion wants the "alright" damage and the movespeed that it gives and almost everyone appreciates the slow. However Trinity Force has that bonus damage on ability cast that you can never remove from it, so if you don't have a spammable ability to activate that passive at least once every 4 seconds, your wasting 1360 gold and an item slot. Given that ricochet has a 4 second CD and can also activate the effect and then consume the bonus damage at the same time, I think its worth it.

And in case you don't know why Vayne doesn't get Trinity Force, it's because her Tumble, which has a 2 second CD at level 5, doesn't add flat damage, it adds damage that scales off of your total AD, so it makes more sense to just build more AD if you want to do more damage with Tumble.
