Lee has pretty good mobility to get into fights
Lee's Q is basically Riven's QQQ+E just in faster. Just to set it into relation..

His actual in fight mobility is rather low.
If Riven would use QQQ+E then she'd have even less in fight mobility.

This is also assuming he still has the energy to do this which he often doesn't. Riven, Yasuo, and Kalista all have spammable short range dashes that allow very high mobility in close quarters situations and in the case of Riven and Kalista, their mobility can be used in any direction at any time.
But in Rivens case she loses her damage if she uses QQQ to engage and her shield if she uses her E. That's far more commitment to engaging than Lee needs to do. Also if she were to engage Riven would have no escape - her Q has 13 seconds cooldown ('spammable') and her he 6 - which is 1 second lower than Lee's Q cooldown.

Calling Lee Sin the king of mobility made sense when he first came out. But now? He's a champion with a strong early game that is really good at getting behind people later in the game and kicking them into your team. But that's all he really does. Lee Sin have strong bursts of mobility but his sustained mobility is rather low, which is why he's played mostly as a tanky initiator and far less as a carry.
Well as I said his sustained mobility (just moving from place a as far away as he can) is higher than Rivens - not even including his higher movementspeed.
This is why if you want to call one champion slippery and the other one mobile you have to call Riven slippery due to being able to use a lot of small dashes but Lee Sin more mobile.
