What is the usual block cipher mode that goes with CTS
There is a NIST definition of CTS (CipherText Stealing) mode in the addendum to NISTSP800-38A.

The title of that addendum answers the question:


  "Recommendation for Block Cipher Modes of Operation: Three Variants of Ciphertext Stealing for CBC Mode".


The paper is also useful to understand that there are many different ways to do ciphertext stealing.
