I recommend just using nested loops to iterate through and add random values. A snippet is below. You'll need to change it to work precisely for your problem. With that said, you can't guarantee randomness and uniqueness. For most uses, you can get by with just using a pseudorandom generator, but there is always the chance for collisions when dealing with randomness.
Also, this will fail with the list embedded in the dictionary, so you'll need to add some extra control-flow logic to deal with that circumstance, but this should help with getting you started.
import string
import random
N = 10 # length of the string
for i in json_var.keys(): # json_var is your json
for j in i.keys():
json_var[i][j].join(random.choices(string.ascii_uppercase, k=N))
