Get files of phone with broken everything
If your ROM and the functionning touch surface of your screen allow it, try to go to settings and activate 0°-90°-180°-270° screen rotation. By turning your phone sideways or upside-down, you might then be able to enable USB debugging again, and proceed to get your files with adb pull.

However, since yout OTG adapter doesn't seem to work, it's likely that your USB port is broken too.
