Only way to stop Garen becoming a monster is to deny him the farm required to get those items he need. So a strong top laner that can consistently stop his passive whenever it goes up and a strong ganking jungler that can dedicate time to top, meaning a strong duo bot is required.
For example, entirely situational;
Top - Rengar (incredible strong top laner that has E to stop his passive and puts bush pressure on garen)
Jungler - Xin/J4 - (Strong Gank Champions)
Bot Lane - MF/Taric (strong bot lane that can handle it without ganks)
Mid Lane - Twisted Fate, Lux, Ori, Xerath (High range safe mids who can live without ganks/can gank bot).
This team can easily stop a Garen for getting out of controlled, and the same method can be used on all top laners that can get out of hand with gold like Singed. The jungler isn't pressured about bot having a hard time due to their natural strengths and mid can safely farm from a distance during the time that the jungle spends top.
If Garen gets shutdown, The jungler and Top can then rotate mid and bot for 2-man ganks and then pressure objectives while Garen stays top to catch up.
