You're basically right. The kami in origami means paper 紙 while the kami in kamikaze means god 神. That doesn't mean you couldn't make a pun about it, but the more fundamental problem is that kamikaze does not mean "suicide attack" in Japanese. The actual word for it is tokkou 特攻, a euphemism that means "special attack".
Kamikaze originally refers to this historical event where a "divine wind" protected Japan from invasion. The term was later used in relation to suicide attacks, but I think tokkou is the word that's more commonly associated with the WW2 suicide attacks in Japanese and kamikaze has kept its original definition.

The Japanese absolutely love word puns.

And they can take it a step further with kanji similarities.

Kami meaning god and kami* meaning paper do have different pitch accent patterns, but that's never kept Japanese speakers from doing wordplay. In fact, the pun works even better in Japanese than it does in English. However, I think they would be confused why someone would want to name it that for a couple of reasons:

1. The suicide bombers from WW2 would probably not be the first thing on their mind when hearing the word "kamikaze". In the first place, the reason they were called kamikaze was because they were likened to the "divine wind" that prevented the Mongols from invading Japan twice. And the few times I've actually heard "kamikaze" being used in Japanese, it's always used figuratively.
2. It's not actually made of folded paper. This is danbooru kurafuto (cardboard crafts), not origami.

*) It becomes "gami" in "origami" because it's the second part of a compound word, but the word on its own is "kami".

EDIT: I just realised something: the company making these is called AirKamuy. "Kamuy" is the Ainu word for god. So if you squint real hard, it does kind of invoke kamikaze. Probably not intentional, though.
