Right.  You have a bit of a misunderstanding here.  "Template" is the 
name of a class.  Your "respond" statement above creates a new Template 
object, calls respond() on that object to generate the string, and then 
throws away the string.  Your Paragraph statement then passes the class,

NOT an object, to the Paragraph class constructor.

You want something like this instead:

    doc = SimpleDocTemplate( ... )
    contents = [ Spacer( 1, 0.15*inch ) ]
    paragraphStyle = get_stylesheets()['Normal']
    text = Template( violation, searchList=[{'name' : 'Tim'}]).respond()
    p = Paragraph( text, paragraphStyle, None )
    ...
Or, if you want to substitute other variables:

    tmpl = Template( violation, searchList = [{'name': 'Tim'}])
    tmpl.otherVariable = 1
    p = Paragraph( tmpl.respond(), paragraphStyle, None )
