A Rakshasa has the following trait:
Limited Magic Immunity. The rakshasa is immune to spells of 6th level or lower unless it wishes to be affected. It has advantage on
saving throws against all other spells and magical effects.
Meanwhile, Animate Objects states:
Objects come to life at your command. Choose up to ten nonmagical
objects within range that are not being worn or carried.
I'm curious if a Rakshasa would be immune from the attacks of these living objects created by Animate Objects as, while the items themselves are nonmagical, they move only because of a magic spell effect.

A Rakshasa's Limited Immunity does not grant them immunity from the 5th level spell Animated Objects, but it is immune to the damage given by those Animated Objects, for a different reason (non-magical damage immunity).
Limited Magic Immunity does not apply to Animated Objects because the spell itself is not dealing the damage - it is done by the constructs created by the spell (another example of a spell that the Rakshasa is not immune to would be Conjure Elemental.)
The Limited Magic Immunity is for direct spell effects against it that consist of spells with attack rolls or saves. This is supported by the next sentence
The reason they are immune to the damage caused by Animated Objects is because Raksasha have Damage immunity to bludgeoning, piercing, and slashing from nonmagical weapons (MM, 257) and Animated Objects give non-magical damage.
