Maybe more of a misinterpretation by AI and/or author than full on hallucination.
"Life insurers can predict when you'll die with about 98% accuracy."
"98%" appears in the citation[1], but as the ratio of actual deaths to expected deaths. (i.e. 98% of the deaths they expected actually occurred.) Some months that figure was ~104%, so it's not a measure of accuracy.
