Is there a correct package type in Library Expert to create an accurate landpattern for this component? SOL was the closest I could find but this is limited to 8 pins.  uploads/71/package_w4.pdf

This is a unique lead form that is not registered in any standard.
 
It would require a mfr. recommended pattern.

Or I would personally calculate the pad length and spacing using the math that is noted in "What's New in IPC-7351C" - download
 
The "Pad Length" math calculation for a Nominal Density Level is (get the pad width and pad spacing from the IPC-7351C paper):
  • Toe = Nominal Terminal Lead Thickness = 0.25 mm
  • Heel = 1.5 X Nominal Terminal Lead Thickness = 0.375 mm
  • Pad Length = Toe + Heel + Nominal Lead Length = 3.725
