For certain Items there are basically two: Randuins omen and Frozen heart. Both of them work really well for most champions. Randuins provides Health, Armor an attackspeed debuff and a movementspeed debuff active while Frozen heart provides Mana, Armor and Cooldown reduction with a strong attackspeed debuff aura.
Basically there is no real hardcounter item to Autoattackers but rather the basic thing you have to buy against these champions: Armor.
As you have already said, CC and kiting will be the most effective things to do against these champions. TT is rather bruiser and CC dominated this means you shouldn't have too much trouble handling an autoattacker, just make sure you focus him right.
Now another Item that is really effective against these champions is Wooglet's Witchcap. The only problem with it: It's only viable on AP or Hybrid Champions. The active will still force the (squishy) auttoattacker to refocus.
