Not a lot of these items and especially champions are played right now, yet people are still complaining about short games. If you PLAY champions that cause long games, there will be long games. The main reasons a Singed can feed so much early and still win is because a.) he can farm easily b.) he can contribute to a team fight very easily and c.) HE CAN STALL VERY EASILY FOR HIS LATE GAME CARRIES! I'm very surprised no one has seen this by now, with the Marksman items being updated. A lot of Hyper Carry ADCs are not getting the light of day because no one is making the correct teams out of them. Something you should notice, as well, is that MAJORITY of these champions are not Supports. If you want a good late game carry, the entire team or a select few champions have to dedicate to it. The reason early game rush comps are so good right now is a.) most of those champions were played last season and b.) it is easier to use those champions without much thought on selecting them.
Placing a Zz'Rot Portal UNDER your own tower can SEVERELY stall a game out since it won't let the enemy minions reach your Tower and it makes it very hard for the enemy team to kill. This can KILL split pushers. Using Banner of Command to create a Super Minion to split push can force the enemy team to go wave clear a lane, making them down at least one member to go clear the wave. Getting ANY AoE item can make it very hard for enemy minions to approach a Tower, especially Stattik Shiv. In this current meta, where majority of teams rely on rushing the game to an end before it's too late, these stall items and champions can extremely hinder their process. A lot of people could say, "Those champions are weak right now." Well, a.) majority of them aren't played enough for anyone to say that and b.) most people don't play them right. People today naturally want to play aggressive, but what if you played very passively. Enemy gets farm, that's whatever. If they were an early game rush comp, they are likely going to get farm anyway. Now, however, they don't get kills because you play very passive. If you get Zz'Rot early, they autofarm for you, so the enemy doesn't benefit from pushing you to your Tower.
THIS IS HOW YOU STALL A GAME! Kills help. Towers help. It's the MINIONS, however, that are the big thing to kill. You kill minions, you stall the game. Another way is to damage an enemy a lot BEFORE a fight happens. Then they won't fight, thus either stalling the game or putting it in your favor to push. Late game carries farm by killing minions and STALLING the game, they get to late game, they carry. Boom. That's it. That is how to stall a game. You build these items and play these champions.
