You can watch this video and noticed the damage of the Dodge dealership(32:11) along I-20. It was made by Canton EF3. This was an aerial damage video of Canton EF3's path.
And notice the damage at 40:50 and 38:00 of this video, checking this from KML on GE, which further confrim that it was the damage from Canton EF3.
Those slabs at 32:11 appear to be metal outbuildings or some structure like that instead of a home. For the other buildings you pointed to those are homes but they were likely surveyed by the NWS as they have destroyed homes on their Canton tornado page that appears to be very similar to the one shown in the video. The reason they probably didn’t get a higher rating is because they were likely poorly-anchored.
