Very strange design. Do you mean to say that the remote script creates concurrent processes all of which block signals? Some signals cannot be blocked. And once a parent process dies the children are then "inherited" by the init process.
The term you want is session leader or session owner. That is the process which owns the terminal.
Sounds like that script should keep ownership of the children and then respond correctly to a SIGTERM signal - tell the children to die, reap them and exit. What you describe is a little on the pathological side, IMO.
One way to deal with it:
If you do not have pstree, install it with homebrew. pstree will show you the process tree your pathological script has created. This means you can kill off all of the Addams family with
BTW
is a last resort, your code really should recognize more standard signals and respond correctly. This kill command does not let the processes shutdown correctly - it just obliterates them - go directly to jail, do not pass Go, do not collect $200.

kill.d
kill.d(1m) USER COMMANDS kill.d(1m)NAME
kill.d - snoop process signals as they occur. Uses DTrace.
SYNOPSIS
kill.d
DESCRIPTION
kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
ber and result.
This program can be used to determine which process is sending signals to which other process.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
Default output, print process signals as they are sent.
# kill.d
FIELDS
FROM source PID
COMMAND
source command name
TO destination PID
SIG destination signal ("9" for a kill -9)
RESULT result of signal (-1 is for failure)
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
kill.d will run forever until Ctrl-C is hit.
