I know nothing about LXDE (or other DEs).

Some clues are the setup's contents, other files on the system with
contemporaneous timestamps, /var/log/installer/syslog's contents, and so on.

This suggests that you or the installer installed ifupdown, and that
it's a top-level package. I would have expected a response more like:
$ aptitude why apt-file
Manually installed, current version 3.2.2, priority optional
No dependencies require to install apt-file
$
but I guess the Provides has some influence. Both ifupdown2 and
netscript can be used instead of ifupdown, though the latter is
for a more specialised scenario.
It's always possible that ifupdown was installed as an alternative
to connman, which is also in the Live image. I don't know which gets
started by default, either in Live, or the subsequent installation
from Live.

That doesn't parse, and without any context, I don't know what it means.
Cheers,
