You should parse the JSON rather than trying to use regex for this. Luckily that’s real straightforward.

import json

text = '{"mob":"1154098431","type":"user","allowOrder":false,"prev":1}'
obj = json.loads(text)  # "loads" means "load string"

if 'allowOrder' in obj:
    obj['allowOrder'] = True
if 'mob' in obj:
    obj['mob'] = 'nonblocked'

result = json.dumps(obj)  # "dumps" means "dump to string"

assert '{"mob": "nonblocked", "type": "user", "allowOrder": true, "prev": 1}' == result
