Well, not really.

It is perfectly ok to have the root signed, but not the TLD. Information
in the response from the root will say "here you have a referral to an
unsigned child zone" so as long as validation is done on the client side
(the one that queries) the response that is signed (the root) will be
validated. Even if the TLD is not signed.

So DNSSEC do protect the root zone regardless of whether the TLD is
signed or not.
