>>> import tkinter as tk
>>> root = tk.Tk()
>>> lf = tk.LabelFrame(root)
>>> lf["class"]
'Labelframe'

Do you spot the difference? The class of the LabelFrame widget is Labelframe 
with a lowercase f. Once you change your database entries to

*Labelframe*font: Helvetica 14
*Labelframe*foreground: red

everything should work as expected.
