This seems like it might be related to python2 vs. python3 according to https://stackoverflow.com/questions/23555906/importerror-no-module-named-html-parser ...

However, my pip seems to be using version 2.7

pip --version
pip 18.1 from /usr/lib/python2.7/dist-packages/pip (python 2.7)

So is the issue that libusb1 is now requiring Python3?

It seems libusb1 version 1.7 has a compatibility issue with python 2.7. However, for me this was not the case with libusb1==1.7.1.
Try running pip install libusb1==1.7.1, then try pip install nrfutil
