You are working on a client management system that accepts and stores client URNs (Uniform Resource Names) as client ids. However, the lookup functionality for clients is not yet implemented. Your task is to implement the `LookupClients` method, which takes a list of keywords as input and returns a list of client URNs associated with those keywords.

The `LookupClients` method is called with the following signature:
```python
def LookupClients(self, keywords):
```
 
You need to implement the following steps in the `LookupClients` method:
1. Initialize an empty list to store the client URNs.
2. Iterate over each provided keyword:
   1. Convert the keyword to lowercase.
   2. Iterate over all the client URNs stored in the system:
      - If the lowercase keyword is found in the lowercase representation of a client URN, append it to the list of client URNs.
3. Return the list of client URNs associated with the provided keywords.

You can assume that the system has a list of client URNs stored in it, and the `self._ClientIdFromURN` and `self._URNFromClientID` methods provided in the code snippet can be used to extract the actual client id from the URN and convert a client id to URN, respectively.

Implement the `LookupClients` method to complete the client lookup functionality.

Sure, I can guided you in implementing the `LookupClients` method as per your requirements. Here's the Python code snippet:

```python
class ClientManagementSystem:
    # ... Existing code ...

    def LookupClients(self, keywords):
        # Step 1: Initialize an empty list to store the client URNs
        client_urns = []

        # Step 2: Iterate over each provided keyword
        for keyword in keywords:
            # Step 2.1: Convert the keyword to lowercase
            keyword = keyword.lower()

            # Step 2.2: Iterate over all the client URNs stored in the system
            for client_urn in self._ClientIdFromURN.values():
                # Step 2.2.1: If the lowercase keyword is found in the lowercase representation of a client URN, append it to the list of client URNs
                if keyword in client_urn.lower():
                    client_urns.append(client_urn)

        # Step 3: Return the list of client URNs associated with the provided keywords
        return client_urns
```

In this code snippet, `ClientIdFromURN` is assumed to be a dictionary in which the keys are URNs and the values are client ids. Also, `URNFromClientID` is assumed to be a method in the same class that returns the URN from the client's id.

If you don't have these methods or list, you need to modify this code accordingly.

Sure, I can help you implement the `LookupClients` method based on your requirements. Here's how you could do it:

```python
def LookupClients(self, keywords):
    # Step 1: Initialize an empty list to store the client URNs
    client_urns = []

    # Step 2: Iterate over each provided keyword
    for keyword in keywords:
        # Step 2.1: Convert the keyword to lowercase
        keyword = keyword.lower()

        # Step 2.2: Iterate over all the client URNs stored in the system
        for client_id in self._client_ids:
            # Convert client id to URN
            urn = self._URNFromClientID(client_id)
            # If the lowercase keyword is found in the lowercase representation of a client URN
            if keyword in urn.lower():
                # Append it to the list of client URNs
                client_urns.append(urn)

    # Step 3: Return the list of client URNs associated with the provided keywords
    return client_urns
```

This method will return a list of client URNs that contain any of the provided keywords. Please replace `self._client_ids` with the actual list of client ids in your system.
