The error message of losetup does not match this theory.

Did you make sure that the file really does not exist when the losetup
command fails ?
E.g. by performing
  ls -ld "${image}"
immediately before
  lb_dev=$(sudo losetup --show -f "$@" "${image}")

Is there a hard reason why you don't show the output of

  losetup -l -a

before, after, and maybe during the script run ?

Have a nice day :)
