expect_dplyr_equal(
    input %>%
      mutate(has_words = nchar(verses) < 0) %>%
      group_by(some_grouping) %>%
      summarize(all(has_words)) %>%
      arrange(some_grouping) %>%
      collect(),
    tbl
  )

works, but if you define the expression inline, it doesn't:

  expect_dplyr_equal(
    input %>%
      group_by(some_grouping) %>%
      summarize(has_words = all(nchar(verses) < 0)) %>%
      arrange(some_grouping) %>%
      collect(),
    tbl
  )

The error you get I think means that base::nchar is being called. I'm not sure if this is a general issue with our nse_funcs calling other nse_funcs, or if this is about the way the aggregation function environment is constructed separately, but it's not good.
