LCS all time Leaders ?

Hey guys new to this boards discussion stuff so not sure where to put this type of stuff, last time I posted something similar to this it was taken down because it was in the wrong section of the boards.
My question is about the LCS all time Leaders- kills-deaths-assists-cs-etc.
Where can I find an up to date all time leader board for those stats from the players. Example of this is last year during the LCS spring split before the CLG vs ? game the all time leader board popped up and it showed aphromoo and the announcers was talking about the player reaching the 1,000 Assist club.
Few games later Xmithie was about to hit the 1,000 club and no leader board to show it nothing. Same thing with Kiwikid and other players passing up other players in Kills-Assists etc. So wondering if there is an all time leader board and where can I find it. Thank you
