Is it possible to use the QuickBooks API to retrieve all transactions of all accounts defined in the chart of accounts, or of an individual account, and to filter by date range?

Not sure if this would help: https://developer.intuit.com/docs/0025_quickbooksapi/0050_data_services/v2/0400_quickbooks_online/journalentry

It is not possible to get all transactions using any V2 api. To get all the transactions you can query individual entities like - Bill, Payment , Invoice etc
