If, however, you run a general query for the NS records:
dig 163.141.in-addr.arpa ns
then you will get an ANSWER section which lists several of our 'ils'

163.141.in-addr.arpa. 3600 IN NS ils022.uopnet.plymouth.ac.uk.
163.141.in-addr.arpa. 3600 IN NS ils001.uopnet.plymouth.ac.uk.
163.141.in-addr.arpa. 3600 IN NS ils009.uopnet.plymouth.ac.uk.
(etc)

The problem is that all these servers are internal to our site. They
cannot be directly queried externally (you get a timeout).
then, you must configure proper NS records for the 163.141.in-addr.arpa zone
So I think my question is what is the resolver doing? Does it use cached
NS records seen in the AUTHORITY section
yes, that is the definition of AUTHORITATIVE data. if your servers are
authoritative for the zone, the given NS records prevail over delegation
from parent zone.
