All the plants that are green have a pigment called chlorophyll. The basic function of chlorophyll is to enable the plants to make their own food. So yes, all green plants are autotrophic.
Taking about making their food, carnivorous/insectivorous plants are also autotrophic. They also make their food using photosynthesis. But, since they usually grow in nitrogen deficient regions, they devour on insects for nutrition. But, they still are autotrophs.

Well to understand this better, it would be beneficial to first analyse what are Autotrophs

Autotroph is an organism that can produce its own food by using light , water and carbon dioxide. And Since autotrophs produce their own food so they are sometimes also called producers.

Now since these characteristics fall in all plants categories thus it is very much true that all plants are Autotrophs because they make their own food by the process of photosynthesis in the presence of sunlight and water. They don't need anyone to make their food. They take carbon dioxide from air, sunlight from the atmosphere and water from the soil and make glucose and oxygen.
