Thanks for doing that.
We don't have NXP HW, so would need more help from you.

I guess I understand the reason:
right now rte_ipsec_session_prepare() expects that
for all modes except RTE_SECURITY_ACTION_TYPE_NONE
security.ctx to be not NULL.
Which as I understand is not necessary for lookaside-proto.
Could you try the fix below?
If it would work as expected, I'll include these changes into v6?
