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.

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
