Do we know if the (apparently Texan) organizer of that fundraiser is affiliated with the victims in any way, or is credible, or might that be a scam?

Sentai Filmworks is a reseller of KyoAni works (amongst others) in the west. They linked to this campaign from their official Twitter account: https://mobile.twitter.com/SentaiFilmworks/status/1151726531...

Sentai Filmworks shared the campaign on their Twitter: https://twitter.com/SentaiFilmworks/status/11517265318966435... so it's at least not someone masquerading as the company.

From what I can tell, yes.

According to their about page [0], they're a licensing/localization company for Japanese animation. Looking at their catalog [1], they've localized various Kyoto Animation productions.

As other comments on this thread have pointed out, the company also shared the campaign on their Twitter account.
