Unless the answer to all of these is unambiguously "the original", then you shouldn't be using such tool on any code, especially on your employer's intelectual property.
Sorry to be so negative about it but this is something that I see skipped over in all discussions related to AI. Just because it's AI does not make it immune to copyright law. You're giving away your code to a 3rd party company under their terms and conditions, and receivig some new code back, again under their terms and conditions. The fact that it uses AI under the hood is irrelevant, you're dealing with a business that produces you an output and you should know the terms before submitting anything to them, especially if you don't own that thing.
