Nope. Whether your local system connects to IPv4 addresses via NAT64-formatted IPv6 addresses is unrelated to DNS lookups of A or AAAA records. If you ask for an A record, you will get IPv4 address(es) back or 0 records, not an IPv6 address. By the way, debugging DNS issues by using nslookup is difficult; try switching to dig and consider the results of running "dig -t a ipv4.l.google.com." and "dig -t aaaa ipv4.l.google.com."
