Scott,
You can do this via the Process Builder. Create the Process on the Case Line Items Object and define the criteria for when it should execute, such as if the record is New and the Credit Approval is populated OR if the Credit Approval is changed. Then, your action should be a field update on a related record and you want to update the record that sits in the Case field on your Case Line Item record. Then, choose to update the Credit Approval Status field on the Case using the value in the Credit Approval field on the Case Line Item record that started the process.
