True, it does not say either way.
What it does say is:
"... will result in the runner being declared out." (As you stated - Rule 8-8-x)
That leaves no reason for the umpire to declare a dead ball as well as the out.
In fact the LBR is NOT mentioned in Rule 9 Section 1 which is "The ball is dead and not in play:"
Again, no justification to rule dead ball.

And for the edification of anyone reading your post as education; NO, In NSA there is NO default to NFHS (or any other) rules.
