Of course they are a tv show:

If the internal metadata are not what plex expects also for a file name, then they won’t be of much use.
You could try Filebot and see if this can make a clever guess and find out which episode is which from the current filename.
Specialty for Looney Tunes:
they use the release year as season number
So the right folder and file name format would be:
TV Shows /
Looney Tunes /
Season 1948 /
Looney Tunes - s1948e07 - A Hick A Slick And A Chick.ext
