I think something will need to be done with the 15k+ items in the odrive trash first.
When you ran that command above, did you recognize the files it listed?
Do they all appear to be in the same folder or are they scattered all over the place.
If you want to output to a text file, so you can read them better you can run this command:
powershell -command "& {$comm_bin=\"$HOME\.odrive\common\bin\";$o_cli_bin=\"$comm_bin\odrive.exe\";$(& \"$o_cli_bin\" status --trash);}" > %userprofile%\Desktop\odrive_trashed_items.txt
This will put the list of trashed items into a file called "odrive_trashed_items.txt on your Desktop.
