Hi, I bought tickets from Liverpool from Lichfield tomorrow which state any rout permitted. Does this mean that I can take the Virgin train to Crewe then the London Midland train to Lichfield rather than the London Midland train all the way?
Your ticket from Liverpool to Lichfield (city or Trent Valley) is valid via Birmingham. So you could take any train to Brum and onwards from there, if you prefer.
And for clarity, "ANY PERMITTED" under route means "you may use any route that is a permitted route", not "you are permitted to use any route".
