Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Currently, the length kernel only works with StringArray. It is reasonable to make it support the ListArray.

Describe the solution you'd like
it should be possible to call something like arrow::compute::length(list_array) and return an array that contains the length of all lists.
