The greatest picks out of lane to counter Jhin include Naafiri, Gragas, and Nidalee. These are all good at countering Jhin with decent win rates over 53%. Even if these Jhin counter picks are not picked in your lane, it's not a good idea to take him into one of these matchups. They will often crush Jhin.
Conversely, if the opposing team brings either Rumble or Maokai, you should strongly think about taking him, as he easily crushes these champs with win rates over 55% against both ofthem.
