1. I suppose that depends on how you define "key management". BitLocker can use AD to escrow SRKs, but that is only one key for disaster recovery. So if one accepts a definition of "key management" that includes keys other than the SRK, one could easily argue that your statement is correct.
2. Yes, that is correct. Although, KTM/KMS does not use AD as a data store for keys (as BitLocker does) - it uses AD for policy management and user authentication.
