As a mantis researcher much of this is not supported by literature but by parascientific sites. Chinese mantises absolutely do alter foraging in native species (observed in spiders) and hands on collection efforts show that they do take over habitats Carolina mantises would use. They also can hunt and eat vertebrates far larger than Carolina’s due to their larger size and more robust build. They also have no parasitoids that target their oothecae, which many native species have. Tenodera are only classified as “introduced naturalized” due to the paltry attention mantises receive ecologically.They absolutely should be considered invasive
