Does this help at all? @Ewan_Opie gave me a python script that gives me templates awhile back.
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
views = UnwrapElement(IN[0])
template_list = []
not_template_list=[]
for view in views:
try:
if view.IsTemplate:
template_list.append(view)
else:
not_template_list.append(view)
except:
not_template_list.append(view)
OUT = template_list,not_template_list
