You can use temporary files like this:
lftp> cls *.csv > listing
lftp> source -e "test -s listing && echo LFTP-COMMAND"
It's not pretty, but works...
You can also try attached patch, which adds this possibility:
glob .empty *.csv && echo "There are no *.csv files"
Suggestions on the command name are welcome (it's not released yet).
