If there is actually only one owner that can approve changes to the package, there's something really weird and unusual about that project setup, or it's someone's internal hobby project that they wrote five years ago and semi-maintain, in which case, I have to wonder why you submitting one-liner changes to it is all that important.
We're all adults, we all work together, we can all work this out. If someone absolutely insists on being an asshole, escalate. It's why you have a manager, and why they have a manager.
My experience is that very few people are unreasonable assholes.
There's always plenty of organizational, vision, strategy, and execution problem in any billion-dollar company, but 'people are unreasonable in code reviews' is not one I'd put in the top 10. It might be something that ruins your day once or twice, but that doesn't make it systemic.
