I'll go out on a limb here and say that RA is not needed for DHCPv6.
A DHCPv6 client multicasts all its messages to the well-known
all-relays-and-servers address. A client needs only its link-local
address to do this. The relay (or server if it happens to be on the same
link) can thus talk to the client in the complete absence of RA.
