As far as I know, we use SqlTransaction to enable rollback if a statement in a batch of commands fails. My question is, is it necessary to use SqlTransaction when retrieving data/using select statements?

No, it is not necessary. Each Sql statement has an implicit transaction. But it can be useful if either the default transaction is not optimal – such as a Read Uncommitted would be better – or if you have multiple reads and you want the data to be consistent – such as separate statements for the summary and detail and you want the detail to add up to the summary.
