You must assume an underlying distribution or you can't do an outlier
test.
Outliers are just unusually extreme data points. They can only be
considered 'unusual' if there is some basis - a distribution assumption
- for deciding what is 'usual'. The assumed underlying distribution
describes what is expected to be 'usual'.
With no distribution assumption, there is no basis for considering any
data point unusual, so the idea of an outlier really has no meaning.
