No. The system source files are optional.

As I understand it the ports that would use /usr/src are ones that
compile kernel modules. lsof would be an exception as I believe it
accesses data structures from the running system to collect it's
information, which are defined in the system sources. lsof should be
compiled against the current system and complains when it isn't.

freebsd-update is configured in /etc/freebsd-update.conf you should find
an entry for Components which should contain src then update.
Another option if you have subversion installed is to checkout the
source tree straight from the svn servers.
