Liz Truss was born Mary Elizabeth Truss, thus her initials are M.T., similar to Margaret Thatcher, and Theresa May, who was T.M.
M+T = 13+20 = 33
England = 33

As for the name she goes by, it screams Jesuit Order.
Liz Truss = 54 / 72 / 144
Jesuit Order = 54 / 72 / 144

Of course, their logo is above the Prime Minister’s door.
