No. A persons life being in danger is not a part of the gay panic defense or the trans panic defense. All that is a required is the killer being attracted to a gay person or a trans person. A trans person doesn’t even have to initiate contact, if someone sees them, is sexually attracted, realizes the object they are trans, they can use that as a defense in court of they then killed them.

Here is a quote

Unlike the legal defense created later and named after it, the onset of the condition was not attributed to unwanted homosexual advances. Rather, Kempf stated that it was caused by the individual's own "aroused homosexual cravings".[15]

The gay panic defense has been used when the victim posed no violent threats to the attackers such as Gwen Araujo, Shelby Tracy Tom, Angie Zapata and others.

You may say it’s not legalizing murder, but when there is an accepted, established, legal defense, in the case of murder, that says it’s okay basses on who the victim is, then I beg the differ.

It claims that seeing and being attracted to a trans person literally made someone crazy and they can’t be held responsible for murdering them.
I would classify that is legalized murder against that group.
