Yes there are such schemes. However they aren't standardized by any means yet. The schemes I'm talking about take part in CAESAR-competition. If you wait ~1 week (hopefully) you'll see if any mode / cipher makes in in the second round. This paper provides you with a good overview over the ciphers. The four ciphers you need are: ICEPOLE (Sponge based) ...

My own two cents on this is that it started with a psychological bias, due to the illusion that AES-ciphering consecutive numbers in CTR mode is a weakness compared to the recursive AES-ciphering in CBC. Actually, I think I remember it was more of less told during that course on Coursera, that a consensus about the inoffensiveness of that counter with regard ...

No OFB_DRBG isn't directly vulnerable to attacks. However from a theoretical standpoint there is one point speaking against it and in favor of CTR_DRBG. Speed. CTR can be parallelized (can encrypt counters in parallel), OFB can't (encrypting state over and over again) So the main reason is speed I'd guess and of course adding OFB_DRBG wouldn't have added ...
