The AA KA codeshares will allow you to get some AA points
Codeshares are for the benefit of airlines, to get sales. Not much in it for passengers
KA is mentioned here:

KA's through-check policy is the same as CX's, i. e., will through-check.
To OP, given that AA members only earn miles on CX / KA if booked in H class or above, the code-share, as @
Mwenenzi pointed out, will allow AAdvantage members to earn miles in more booking classes.
