Filet between list of curves

Hi everybody,
I’m starting with GrassHopper but i’m having some trouble with the intersections between my curves.
I have my initial lines that i have to do an offset on it. Then i need to do a filet between those lines, and that’s what i can’t achieve.
I think the main problem is that my curves are in a list but i dont have a choice.
I have the intersection points but i cannot split the curves with it.
This file is going to be used with hundreds of curves so i cannot select the curves one by one.
Is there a solution for this?
Thank y’all for your help

Thank you for answering but i already saw those topics. And there the lines have an intersection already, in my case it isn’t.
