The ESRB sort of has something like PEGI's "multiple, motiveless killing" and "violence towards defenceless people". That's part of what "Intense Violence" is defined as. When a game has the other half of "Intense Violence" (violence causing dismemberment), but the actual violence would qualify as Fantasy or Cartoon, they mark it as just "Violence". Presumably, the same would be done with Undertale and it would be rated T.
