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.

script
script(1) User Commands script(1)NAME
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.
ATTRIBUTES

script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
privileged user, that is, root. Be sure that typescript is not a link before running script.
