There is nothing in the lore specificly connecting spriggans to anything. They do come broadly under Kyne's sphere of nature, of course, since they are basically dryads in elemental form.
FYI: The name comes from Lawrence Watt-Evans's Ethshar series (With a Single Spell & The Spriggan Mirror being the two most relevant), but gamesas spriggans and Ethshar spriggans have absolutely nothing in common beyond the name.
