Yes, the pitcher of Nepenthes is a modified leaf, not a stem. It is a specialized structure that has evolved to attract, trap, and digest insects for additional nutrients.
Stem pitcher plants, commonly known as Nepenthes, are a genus of carnivorous plants characterized by their unique pitcher-shaped leaves that trap and digest insects. These plants typically have long, climbing stems that can reach several meters in length, allowing them to grow in vertical spaces. The pitchers vary in size and shape, often featuring colorful markings to attract prey. Nepenthes thrive in nutrient-poor environments, primarily in tropical regions.
Nepenthes rajah reproduces through the production of seeds. The plant flowers, and once pollination occurs, seeds are created within its pitcher-shaped structures. These seeds can then disperse and germinate to grow into new Nepenthes rajah plants.

Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
According to a report from The Sun on 19 August 2009, scientists in the UK have discovered a mammal-eating plant that they believe is the largest and the rarest of the meat-eating plants, a pitcher plant named Nepenthes. It grows only on the high, windswept slopes of Mt Victoria in the Phillipines. This plant is believed to be the largest meat-eating flora in the world. It is green and red and has a stem that can grow up to 4ft long. See the related link for the article.

Nepenthes gantungensis was created in 2010.
There are currently five recognized genus with the common name of pitcher plant: Cephalotus, Heliamphora, Sarracenia, Darlingtonia, and Nepenthes. Cephalotus species: 1 (monotypic) Heliamphora species: approx 16-17 Sarracenia species: 11 Darlingtonia species: 1 (monotypic) Nepenthes: 120 exactly. Total: 133
Thorns are leaf modifications in opuntia (a type of cactus) and a stem modification in bougainvillea. So it depends on the type of plant.
