Hello @pixel9ahype , welcome to the /e/OS forum. 
You are not the first asking for the Pixel 9a, see e.g. this thread: The pixel 9a -- no news is not good news
TL;DR: As of November 1st, 2025, LineageOS does not support the Pixel 9a yet, so an /e/OS release is highly unlikely in the near future, I am afraid.
