user5496: I want to use CLI to submit transactions and want to use an alternative tool that isn't cardano-node.

You can use the Blockfrost API.
It has a free level that might even meet all your needs.
Using curl you should be able to cook up what you need using the CLI but without the need for a Cardano node.
Here is the doc page for "Submit a Transaction":
