No. ZFS can create inodes until the filesystem is full. >I've tried using --mkfsoptions="-N value" mentioned in lustre 2.0 >manual, but it fails to accept it.

Since the "free" inode count is just an estimate for ZFS, and is quite a big guess when the filesystem is new, but gets more accurate as the filesystem has more inodes created. For 80GB SSDs with about 2KB/inode (usable space) you might get at most about 20M inodes for such a filesystem.
