I think it's implied that Olivander makes the wand for her in part becuase her blood status is higher than that of Hermiony and Shamus. It's pointed that he doesn't make them wands, and implied throughout that Olivander isn't the lightest of wizards.
Wood, Core, and Length[]
According to this site: https://bityl.co/MgmW
Luna's second wand is made from blackthorn wood, Luna’s one-of-a-kind wand stands at an impressive length of 12 ¾ inches. It boasts a core material unlike any other – a strand of exquisite mane hair from none other than a Thestral, which adds an air of mystery to Luna’s wand. —The preceding unsigned comment was added by PaulStSmith (talk • contribs) 18:12, 1 December 2023 (UTC).
