@Dr-Sassi Thanks for the additional tips. I managed to reduce the spline points down using your technique and after applying the volume builder + and changing SDF smooth to about 90% strength, I got smoother lines!
I made some materials with a texture node that includes the pattern references I generated earlier in order to do a Camera Mapping Projection of the pattern for easier tracing (though I did have to whip out the pen tablet to draw them by hand).
Thanks for all the help! Feel free to mark the thread answered.
