I just installed LineageOS 14.1 using TWRP.

  3. Navigate back, open Developer Options.
  4. Tap Root Access.
  5. Select Apps or Apps and ADB.

Now you have root and Titanium Backup finds it:

I just found I had to switch from ADB only to Apps and ADB. Not sure why, since the issue was with ADB itself.
