LVP means luxury vinyl plank. LVT means luxury vinyl tile. The letters sound like two different materials. On FloorBox they are mostly two shapes of the same idea: a vinyl floor that looks like wood boards, or a vinyl floor that looks like stone or tile. Shop Vinyl Planks and Vinyl Tiles. For the full map of vinyl types (plank, tile, sheet, core, basement), start with What Are the Types of Vinyl Flooring, and Which One Fits a Basement? Still choosing between laminate and vinyl? Read Should I Choose Laminate Flooring or Vinyl Planks, and Is Laminate Real Wood? Below, the one question is which shape fits which room.

Three things you can see on the product page:
The core can be the same idea on both shapes. SPC (stone-plastic composite) shows up on both plank and tile examples below.
The Planchers 1867 Vinyl Plank Evolution Magma XL Series Helka Click Lock 7" x 48" is a wood-look plank: 7" × 48", SPC core, Click Lock, Underpad Attached: Yes (EVA Foam), Waterproof: Yes, Grade Level: On, above and below, Pet Friendly: Yes, Thickness 4 mm, Wear Layer 12 mil (0.3 mm). If you want long boards that click together with the pad already on, this is the shape. For how the click works, see How Does Click Vinyl Flooring Lock Together?
The Planchers 1867 Click Vinyl Tiles Evolution Azura Travertine Bone 12" x 24" is a travertine-look tile: 12" × 24", Material SPC Vinyl, Installation Method Click, Thickness 4.5 mm, Underpad Attached: Yes (1 mm), Wear Layer Thickness 0.5 mm. Same family of idea as a click plank — stiff core, lock, pad — but in a tile format that reads as stone.

When you want a tile look that sticks to the floor, and you care about a softer feel than ceramic. The Centura Vinyl Tile UltraCeramic by American Biltrite Natural Travertine Warm Silver 12" x 24" lists Glue Down, 12" × 24", Thickness 4 mm. Its description says it is an alternative to ceramic or stone, warmer and quieter, does not crack, and is available with or without grout. Underpad Attached: No — so there is no pad glued under the tile; the adhesive is the install method.
Both Azura and UltraCeramic copy the look of travertine. For what real travertine is, read What Is Travertine, and Is It a Good Choice for Floors?
Walk the room in your head:
Neither shape is "better" in the abstract. Match the look of the room, then match click vs glue to how you want the floor to sit.
