Europe also just doesn't need split-phase systems. A regular outlet will provide 230V @ 16A, or about 3.7kW. That's enough for virtually all household appliances, and single-phase 32A circuits for 7kW stoves are quite common too. Households these days often do have a 3-phase hookup, but it's quite rare to have 3-phase equipment. Maybe a stove, and with the energy transition larger solar setups, electric car chargers, and large heat pumps. But most of the time that 3-phase hookup is just treated as three separate 1-phase sections.
