Probably others already answered this, but here goes anyway.

No, but brltty-x11 is listed. You can safely purge brltty, brltty-x11 and
ubuntu-mate-desktop. The later depends on brltty which depends or
recommends (I'm not recalling which) brltty-x11, so there is your problem.
The good news is ubuntu-mate-desktop is a metapackage, so you can safely
remove it without removing your full desktop. I would not use dpkg for
this. Instead, install Aptitude and do this:
aptitude -q purge brltty

Not that I know of, but it's not necessary. See above. If you remove
pulseaudio, it also removes the desktop metapackage. It's mostly harmless.
However, you have another option. Run the following commands:
dpkg --force-all --purge brltty brltty-x11
aptitude -q install brltty brltty-x11
That won't remove the desktop metapackage.
