As someone whose a close friend ended themselves, I can offer some perspectives.

"Die by suicide" is preferable to "commit suicide" or "killed themselves" because it shifts the cause from the person to the circumstances that led to the act. In many cases, suicide is not intentional, but is brought upon by (mental illness / other circumstances) in which the person sees suicide as the only way out. Therefore, "kill themselves" implies they willingly choose suicide and is responsible for it, as opposed to "die by suicide", which implies the person is a victim.

This article provides a good overview on why this is the case, and I resonate to it a lot: https://www.nbcnews.com/better/health/why-mental-health-advo...

For pedantic readers, it's not clear in this case if the person chose suicide by themselves, or were driven to it. Regardless, I'd still err on the caution side.

That would be a good way to avoid the mental health issues that are currently in overload state. But … It won’t solve the problem by soft-pedaling with different words.
