I don't think you're looking at this logically. NONE of them can stop Tornadus-T from switching out. By your logic, Genesect wouldn't have been banned because "It's not our problem if it gets a Special Attack boost."Ok, I am only going to say this once so let me make myself clear!
A COUNTER can switch into a pokemon, and pose an immediate threat the the pokemon it switches into. A CHECK can remove the said pokemon but may not be able to safely switch in.
Jirachi counters Tornadus-T, it threatens Body Slam paralysis which shits on Tornadus-T's life. Jirachi can switch into any of Tornadus-T's moves or move combos. Jirach is what we call a HARD COUNTER due to reliable recovery.
Rotom-W counters Tornadus-T. It threatens the OHKO with Thunderbolt / Volt Switch. You are sitting here telling me that Rotom-W doesn't counter Tornadus-T because Rotom wash is 3HKOed by Specs Hurricane. Guess what, Tornadus-T is OHKOed by electric attack. That makes Rotom-W a counter. It is not my fault, or the fault of anyone on the voting "committee" that a skilled Torandus-T user can outlast a Rotom-W. Guess what, it works both ways. However, Rotom-W is a counter because it switches in and threatens a OHKO. Case point. END OF DISCUSSION.
Jolteon counters Tornadus-T. It threatens a OHKO with Thunderbolt / Volt Switch. It doesn't matter if it only switches into Hurricane once. It lives any of Tornadus-T's attacks and OHKOs in return. That is a counter. Again, the rest is not my problem. Jolteon is a counter. Deal with it.
Zapdos counters Tornadus-T. It threatens a OHKO with Thunderbolt. It switches into anything Tornadus-T has and has reliable recovery to boot. It can do this multiple times a match. Zapdos is a HARD COUNTER. It is not my problem if you don't want to use Zapdos. The truth is, Zapdos has the bulk and typing to wall a helluva lot more than just Tornadus-T so don't bitch at me because you refuse to use it.
Thundurus-T counters Tornadus-T when equipped with a Choice Scarf. It threatens a OHKO with Thunderbolt / Volt Switch / Thunder. It can switch into any one of Tornadus-T's moves.
Metagross (shaky) counters Tornadus-T. It counters if you run it on Rain. It can switch into Tornadus-T, and threatens a good amount of damage with Pursuit or just general high power Meteor Mash. Not my problem if you don't like Metagross.
Magnezone checks Tornadus-T. It can live any one of Tornadus-T's common attacks and threatens a OHKO with Thunderbolt. Again, not my problem if you don't like Magnezone.
Weavile checks Tornadus-T. It can't switch in, but threatens a OHKO with Ice Punch. It also can Pursuit a fleeing Tornadus-T for a crap ton of damage. Not my problem if you don't like Weavile.
Mamoswine checks Tornadus-T. It can't switch in, but it threatens a large chunk of damage with Ice Shard. After SR, Ice Shard can OHKO. Not my problem if you don't like Mamoswine.
Choice Scarf Keldeo / Garchomp / Terrakion checks Tornadus-T. It can't switch in, but it threatens a OHKO with the appropriate move. The rest is just not my problem.
Ninetales checks Tornadus-T. It can switch into all of it's moves, removes rain, and can retaliate for heavy damage. Again, not my problem if you don't like sun.
Quit your bitching and move on. Yes, Tornadus-T is good but it doesn't even work without Drizzle. Tornadus-T against a Sun / Sand team? Doesn't work nearly as well. I love how no one brings that up.
