I found a single felt-wrapped plastic clip in the floor on the driver's side after the dealer replaced the Takata airbag on the passenger side. 2007 ES350. Pictures attached. Anybody recognize this? I'd like to be sure it came out of the dash before I have my talk with the dealer service department.

 

That is a piece out of the dash. Take it in and ask them, they should be able to pop it back in for free.
