The optics obviously look shitty right now, but throughout her entire career Taylor has always been incredibly kind to her fans. It's very uncharacteristic of her to not help the family or even put out a proper statement, and I don't believe she would ever choose to ignore a tragedy like this.
The only logical explanation is her legal team are preventing her from doing that, which is obviously awful, but she probably needs some time to pass or the legal issues to be worked out before she can say/do anything.
