Yes. As stated in another answer, you can use "timeout" command
(see "man 1 timeout").

But there is also built-in lftp command "at", so you can run something like:

lftp <<EOF
at 06:00 -- exit kill &
get -c http://example.org/huge-file.zip
EOF

Exactly at 6am lftp will kill running jobs (the "get" job) and exit.

You can also use "at" to start jobs, set rate-limit, etc.
For example:

lftp <<EOF
repeat --weak at 00:00 -- set net:limit-total-rate 10M &
repeat --weak at 06:00 -- set net:limit-total-rate 100k &
get -c http://example.org/huge-file.zip
EOF
