I thought about it, but a) they scan broadly for people who are at-risk of being triggered themselves, so with my recent history I likely wouldn't be accepted b) I realised that I wouldn't be able to act substantially differently and be retained, so essentially I'd be being trained to hurt and lie to people knowingly. I do think suicide hotlines are fine at acting as a sort of temporary stopgap for a certain type of redirectable case, but they're deceptively advertised and do a lot of harm to the recurrently suicidal.
One of my goals was to be a particular type of clinical worker that doesn't exactly deal with mental health or social work (vagueness) but can end up as part of the pipeline to both, and I suffered a real emotional crisis over the same realisation - that while I would be delivering useful advice to people, I would be expected to pass the buck on their emotions to people who might not be able to help them, or else deflect.
Not gonna lie, volunteering at these places is actually really good resume experience for a lot of the latter kind of jobs (or their degree programs). It was explicitly listed for mine. Gives you a gloomy outlook on what these people end up doing.
It's not just a matter of expectation either, you would be considered to be putting the person at risk.
