It would be handy to have an image of what you are trying to make.
But in really simple terms, a 19 point spline is simply a single spline which has been patterned a number of times.

You'd need to know the width of a spline, and the inside and outside diameters to begin making the tool you need.

This spline as 27 points, but I assume your 19 point option would be a lot like it once you determine the important dimensions: https://grabcad.com/questions/1-3-4-27-spline-rotor

These are also sold: https://www.amazon.com/Kohler-1018647-KOHLER-K-1018647-Adapter/dp/B002J36R2Q?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-ffsb-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B002J36R2Q
I did not count the number of teeth/splines
