The child of an illegal alien would NOT be a NBC because they were not under the authority of the government at the time - just as an ambassador or foreign soldier is not. All the rest? NBC.

8 FAM 301.1-1 INTRODUCTION
(CT:CITZ-50; 01-21-2021)[...]
(a) Acquisition of U.S. citizenship generally is not affected by the fact that the parents may be in the United States temporarily or illegally; and that; and
(b) A child born in an immigration detention center physically located in the United States is considered to have been born in the United States and be subject to its jurisdiction. This is so even if the child's parents have not been legally admitted to the United States and, for immigration purposes, may be viewed as not being in the United States.
You should know very well that subsequent law cannot redefine a term used by the US Constitution *UNLESS* it is a constitutional amendment.
You don't get a back door into redefining words in the US Constitution.
