You can use the String's replace method.

If you want to remove only the first encounter of 'null' you can use this:

listChat.text = listChat.text.replace("null", "");

If you want to remove all encounters of 'null' this will do it:

var stripNullPattern:RegExp = /null/gi;
listChat.text = listChat.text.replace(stripNullPattern, "");

If you only want to remove null if it's in the first four characters use something like this:

if(listChat.text.substring(0, 4) == "null")
{
    listChat.text = listChat.text.replace("null", "");
}

Check the AS3 reference for more info:
