Use the json module and str.replace.

import json

d = """{
    "xyz" : {
        "SERVER": "xxx@localhost",
        "WEBHCAT_SERVER": "http://qws.qs.i5.internal.cloudapp.net:50111/templeton/v1/"

    },
    "SNSPARK": {
        "PROJECT_BASE": "/home/databrik/newdp/projects",
        "SCRIPT_BASE": "/home/databrik/newdp/scripts",
        "DATA_FILE_BASE": "/home/databrik"
    },
    "LOCAL": {
        "PROJECT_BASE": "/home/pica/Installation/databricks/platform/projects",
        "SCRIPT_BASE": "/home/pica/Installation/databricks/platform/scripts",
        "DATA_FILE_BASE": "/home/pica",
        "CB_URL_BASE": "http://11.222.222.111:3017/api/v1"
    },
    "DEFAULT_BACKEND": "LOCAL",
    "public": {
        "USE_LDAP": false
    }
}"""

d = json.loads(d)
for k in d["LOCAL"]:
    d["LOCAL"][k] = d["LOCAL"][k].replace("pica/Installation", "louis")

print(json.dumps(d, indent=2))

Output:

{
  "SNSPARK": {
    "PROJECT_BASE": "/home/databrik/newdp/projects",
    "SCRIPT_BASE": "/home/databrik/newdp/scripts",
    "DATA_FILE_BASE": "/home/databrik"
  },
  "DEFAULT_BACKEND": "LOCAL",
  "public": {
    "USE_LDAP": false
  },
  "LOCAL": {
    "PROJECT_BASE": "/home/pica/louis/databricks/platform/projects",
    "SCRIPT_BASE": "/home/pica/louis/databricks/platform/scripts",
    "DATA_FILE_BASE": "/home/pica",
    "CB_URL_BASE": "http://11.222.222.111:3017/api/v1"
  },
  "xyz": {
    "WEBHCAT_SERVER": "http://qws.qs.i5.internal.cloudapp.net:50111/templeton/v1/",
    "SERVER": "xxx@localhost"
  }
}
