The following worked for me. No prompt and no user interaction.
sudo /Adobe\ Creative\ Cloud\ Cleaner\ Tool.app/Contents/MacOS/Adobe\ Creative\ Cloud\ Cleaner\ Tool --removeAll=All
or
sudo [Path to Adobe Creative Cloud Cleaner Tool.app]/Contents/MacOS/Adobe Creative Cloud Cleaner Tool --removeAll=All
The problem I found was copy/pasting the command from this site into the terminal, the two dashes/minus/hyphens "--" between 'Tool' and 'removeAll=All' were not the same as what was naturally type in the terminal. When I replaced them and changed to '=All' it worked.
Hope this helps!
Cheers
