Let's say I have nodes A, B, C ... Z. I want for nodes C to Z to die when A dies, but for B to continue executing and ignore that A died. I know I can use the required="true" argument on A in the roslaunch file to kill other nodes when it dies, but is there a way to tell roslaunch to not kill B?

No, roslaunch cannot do this.

If your launch process is this complex, you may want to rethink your launch process, use separate launch files or write your own process management. Roslaunch has an API that may be useful.
