Sounds like you have the Curt 4 Bike Rack # C18030 on your 2015 Toyota Sienna. First, for the anti-rattle lock, if you want to replace just the bolt, the official Curt part is # C22321 which has a nice bracket for extra sturdiness. If you're looking for a locking option, then the SportRack Anti-Rattle Hitch Lock # SR0901 is a confirmed fit for Curt bike racks.
As for replacing the shank on your Curt 4 Bike Rack # C18030 to make it a pure 2" bike rack, Curt does not offer that part. If you keep the included adapter sleeve on your rack, then it will function as a 2" bike rack. If you lose that adapter sleeve, Curt does not make a replacement part, so what we do is use the hitch receiver sleeve # HT02. I attached some videos below if you want to check those out including my review of the Curt Premium 4 Bike Rack which is essentially the same rack, but with a different arm design.
