Getting null pointer exception in webservice class?

Question

I am getting

System.NullPointerException: Attempt to de-reference a null object

Inside this part you should declare the creator function to instantiate the lists of the class, otherwise when you are trying to add values there you get a null pointer since the responses lists haven't been instantiated.

global class responseOfWs{
        List<accList> accList;
        List<leadList> leadList;
        List<conList> conList;
        webservice string errorFound;
ResponseofWs(){
  accList = new List<accList> ();
  leadList = new List<LeadList> ();
  conList = new List <conList> ();
}
    }

You didn't really need to "copy" the lists, as you could have simply written:

webservice static responseOfWs getCaseDetailsFromcsNum(requestKT csNum){
    csNum.inputName = '*'+csNum.inputName+'*';
    List<SObject[]> results = [
        FIND :csNum.inputName IN ALL FIELDS RETURNING  
        Account (Name,Phone,PersonEmail),
        Contact(Name,Phone,Email),
        Lead(Name,Phone,Email)];
    responseOfWs res = new responseOfWs();
    res.accList = (Account[])results[0];
    res.conList = (Contact[])results[1];
    res.leadList = (Lead[])results[2];
    return res;
}

If you don't want the Id values to be returned, you can scrub those out:

for(SObject[] resultList: results) {
    for(SObject record: resultList) {
        record.Id = null;
    }
}

You can do this before building the 'res' variable.
