I'm experiencing a somewhat similar issue from within SharePoint Online.  I found a way of deleting the item that may help. 

If you have access to the SharePoint library directly, you should be able to select Version History from the options menu for the item in question.  Here's how I was able to get rid of the problem child:

 Next, I select Delete All Versions:

 Once I did that, I then opened the "locked" version in Word and saved it.

Now I can go back to the list in SharePoint and delete the item.  

Your mileage may vary on this but it worked for me.
