That seems to be (an expansion of) a little bit from a poem, Dumt fôlk by Gustaf Fröding: https://sv.wikisource.org/wiki/Dumt_f%C3%B4lk https://sv.wikisource.org/wiki/Dumt_f%C3%B4lk. But that only has "...e å, å i åa ä e ö" -- not the bit about "å i öa ä e å" from that tongue-twisters page, which seems to be a later addition. Ungrammatical, too: I'm sure even värmlänningar would say "på öa", not "i öa". (Oh, and "e" is of course a contraction of the indeterminate article "en", a/an.)
