Components depend on the theme.  In some themes, Radiobutton does have a 
border.  On Windows 10, I ran

 >>> for s in style.theme_names():
	style.theme_use(s)
	style.theme_use()
	style.layout('TRadiobutton')

Theme names are ('winnative', 'clam', 'alt', 'default', 'classic', 
'vista', 'xpnative') with 'vista'the default. Outputs were the same as above

'vista'
[('Radiobutton.padding', {'sticky': 'nswe', 'children':
[('Radiobutton.indicator', {'sticky': '', 'side': 'left'}),
  ('Radiobutton.focus', {'sticky': '', 'children':
[('Radiobutton.label', {'sticky': 'nswe'})], 'side': 'left'})]})]

except for this

'classic'
[('Radiobutton.highlight', {'sticky': 'nswe', 'children': 
[('Radiobutton.border', {'sticky': 'nswe', 'children': 
[('Radiobutton.padding', {'sticky': 'nswe', 'children': 
[('Radiobutton.indicator', {'sticky': '', 'side': 'left'}), 
('Radiobutton.label', {'sticky': 'nswe', 'side': 'left'})]})]})]})]

.theme_names() only displays the themes for the OS.  I believe that 
there is a way to access themes for other OSes (unix, mac) but don't 
remember.
