Ok, so I know I have faced this team a few times in the past, and I can definitely say that it is well construsted. There are a few things that stand out to me that could possibly be addressed to make it better.
First, while I personally never used it, as you mentioned, opponents running your own Tomohawk sets or other Rapid Spin Tomos can give you a bit of trouble. Tomohawk can get in easily on half your team, which is not that unusual, and not a huge problem by itself, but with Rev being your spin blocker, you will be hard pressed to stop it from getting rid of your hazards. Really, the only way to prevent a Spin Tomo from spinning is with a double switch to Rev and then Kril. While in general, Kril and Latias do a good job checking Tomo, spin variants will give you a headache when it comes to keeping your hazards down.
Kitsunoh is another Pokemon that has the potential to cause problems for your team, and is honestly the biggest concern for you in my opinion. While Politoed isn't too threatened by it, it is loath to switch in against it repeatedly, thanks to the high chance of a defense drop from ShadowStrike. A Tomohawk without Prankster Substitute also lacks the ability to tank hits from Kit. Rev and Latios are both scared of its STAB super effective moves, and Ferrothorn can't do much to hurt it and has to beware of Will-o-Wisp. Krill is the only one who can really switch in feeling safe most of the time, and even it has to be careful of the occasional EQ.
While the team is fairly solid already, if I was to make any suggestions, it would probably be to switch Revenank out for a Kitsunoh, probably one with Earthquake. Unlike Rev, Kit can easily spinblock most Tomo. Its not exactly doing the most damage back to it, but unlike Rev it can come in without fear, giving you more opportunity to get to an apropriate counter before it spins. Spinning Mollux can give you problems, much like Spin Tomo did to Rev, but Earthquake can usually take care of them before they can do too much. EQ is also nice insurance against opposing Krilowatt, which could cause you trouble later in matches, especially if Ferro is down. Kit also can provide nice support with moves like Will-o-Wisp which much of the team can appreciate. Obviously, this would mean the loss of priority moves on your team, which could be a problem in certain situations, but I don't feel would be too big a deal in general. Overall this is more of a pick your poison change than anything else. Its not a fix all that will make it a perfect team, but it replaces some of your problems with other ones that might be more managable.
As a side note, I absolutely love that Latias set in CAP. I have used it multiple times myself and it is just fantastic.
