The TDM application level has no control over what space is used in the Database log files.
Even if you split this up into multiple jobs this will not change the amount of space used in the database log files.
the files are not shrunk when a job is completed.
They are only shrunk after a backup and a purge which is done by the database team.
You will need to contact your DBA to handle this process so it does not impact your operations.

change the recovery model of that database to Simple and the SQL Transaction Log will be truncated automatically after each Checkpoint.
