Heat olive oil in a saucepan over medium heat. Add tomato paste and stir gently, being careful of hot splatters! Cook for a minute, then add Italian seasoning, pepper flakes, and salt & pepper. Cook for another minute. Mix crushed garlic with a splash of water; add to the pan. Continue cooking, stirring as necessary, until mixture is thick and fragrant. Stir in the wine, then the water. Cook until spreadable viscosity is reached, adding more water if needed, then add dill and remove from heat. Set aside and let cool.
