SQL Server 2014 :: Best Way To Pull Login Data For Auditing System Wide?

I am trying to import this years worth of failed logins and last successful login for each user out of the logs using master.dbo.xp_readerrorlog. The script essentially loops through the linked servers I have on my DBA box and reaches out for the log data. It works, but here is the error I am getting on most of our production servers:

OLE DB provider "SQLNCLI11" for linked server "AWSCADENCEDB01" returned message "The partner transaction manager has disabled its support for remote/network transactions.".

Msg 7391, Level 16, State 2, Line 17
The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server "AWSCADENCEDB01" was unable to begin a distributed transaction.

I know how to enable distributed transactions on the servers that error out, but if it is not needed for anything other then my audit script, I doubt the business will approve me turning on distributed transactions at those locations (so I am not even going to ask).

I am attempting to setup a singular audit .rdl with the information I want to review quarterly.

CREATE PROC [dbo].[Import_Login_Data]
AS
IF EXISTS (
SELECT 1
FROM master.sys.servers
WHERE is_linked = 1
