SELECT from Clustered Columnstore results in LOB Reads
Multiple sources appear to indicate Columnstore Indexes store its data as LOB data, which is happening in this case.  My understanding and take-away is that it should always be expected for LOB reads to occur when using Columnstore indexes.

What's the anatomy of a Columnstore index?

How to use Columnstore indexes in SQL Server

Inside the SQL Server 2012 Columnstore Indexes

SELECT      COUNT([partition_number]) AS [Number of Partitions],
            SUM([in_row_used_page_count]) AS [SUM_in_row_used_page_count],
            SUM([lob_used_page_count]) AS [SUM_lob_used_page_count],
            SUM([used_page_count]) AS [SUM_used_page_count],
            SUM([row_count]) AS [SUM_row_count]
FROM        [sys].[dm_db_partition_stats]
WHERE       [partition_id] IN   (
                                    SELECT  [p].[partition_id]
                                    FROM    [sys].[partitions] AS [p] 
                                    INNER JOIN  [sys].[objects] AS [o] ON [o].[object_id] = [p].[object_id]
                                    WHERE   [o].[object_id] = 971254615
                                );


Results:

Number of Partitions SUM_in_row_used_page_count SUM_lob_used_page_count SUM_used_page_count  SUM_row_count
