Don't called your project *Zilla. The copyright owners of Godzilla are known to go after everyone who tries to use the "Zilla" suffix. Mozilla learned its lesson long ago and had to negotiate a special agreement.
As an 10 year Mozilla veteran, I agree you should switch domains/project names. Mozilla was able to negotiate a deal for a number of reasons- Mitchell herself is a lawyer, the project is a NPO, and probably other reasons too, but it's not worth the effort to defend a slightly infringing name against the copyright holder in this case.
How would this even remotely relate to Godzilla or it’s copyright?
It’s not even close to a big scary nuclear fueled monster.
I’ll note that the only TM case they ever lost was against a company selling trash bags named ‘trashzilla’, partially because it did not constitute a danger to Toho’s business interests.
Edit: Uh, I missed the logo. Definitely a problem.
When you consider the most recent Godzilla film, Minus One, is the 37th in that franchise, and was not only nominated for an Oscar, and may be it's most lucrative, you can see why Toho would aggressively police that copyright.
It's pretty clear that "zilla" is a genericised word suffix, cf "bridezilla", in English.
Whilst it seems to originate with Godzilla -- which honestly also doesn't seem to associate with a particular company but instead I would say it's a now traditional monster name in stories, like Dracula -- noone is confusing this with any Godzilla franchise. These sort of attempts to own a word sten, across trademark categories, are an over-step that legislators need to rein in IMO.
Does the recent Sky trademark battle speak to this?

This is a really weird take. Dracula is in the public domain, while every piece of Godzilla media is still copyrighted and trademarked to Toho, one of the big four movie studios of Japan.
