The fact that LSD is of the family ergotamine, and that the fungus ergot which happens to contain ergotamine has caused deaths, is a meaningless statement.
Chemistry and psychopharmacology is an incredibly complex topic, and it isn't as simple as saying "Well, X is related to Y, and X causes A, ergo Y must cause A."
There's a concept called "structure-activity relationship" (SAR) in medicinal chemistry, and it's the study between a molecule's "physical" (for lack of a better word) shape and it's effects.
If you aren't familiar with medicinal chemistry, as a human your assumption is probably to go "Well, X molecule is really close to Y molecule, so they must do similar things."
Unfortunately, this just is not how it works.
Look at amphetamines. Saying something is an "amphetamine" is meaningless, because what an "amphetamine" is and does is entirely dependent on _which_ amphetamine it is.
Regular "amphetamine" is a simple stimulant.
Then you have psychedelic amphetamines, like 2,4,5-Trimethoxyamphetamine, which aren't stimulatory at all and act more like LSD.
Both of them are, by definition, "amphetamines", but no commonality in terms of effects/psychoactivity.
A single structural change makes the difference between being benign or being incredibly toxic, being a stimulant or a psychedelic, etc.
You can't talk about these things with sweeping generalizations.
The only way to have a legitimate, rational discussion about chemicals is to completely rid the physical structure from your head and discuss it in terms of it's receptor affinity, ligand-binding, and Ki values.
Everything else is complete pseudoscience and quackery.
