generally, I concur with Andrew's comment about this: life insurance on itself is different from considering death in a clause inside a shipping / commercial insurance contract. It makes sense to specify what happens if a contracting part dies.
But about your own source, wiki cites on reference [11]: https://www.lassuranceenmouvement.com/2021/02/11/lassurance-vie-des-femmes-enceintes-a-genes-en-1427/
First, it is about XV c., after the Black Death, very late middle ages. And, it is mainly about insurance for pregnant women against death due to pregnancy or birth complications. The article also explains that the wider context could be recovering the significant cost of the bride dowry if she dies during birth.
As it is a specific context, your own source does not tell anything about life insurance against disease during the black death.
PS: In some cities in Brazil, some cars are robbed so often that insurance companies just do not insure them. One owns them at his own risk. I doubt any of today's companies would insure against a disease as lethal as the black death was in the middle ages.
