rpc.statd and portmap aren't the exclusive domain of NIS. Both are
enabled by default and used by NFS as client or server. I think they
could be disabled by default instead of being enabled by default.

You can disable both services:

# chkconfig --level 12345 portmap off
# chkconfig --level 12345 nfslock off

If you don't want the NFS server:

# chkconfig --level 12345 nfs off
