He likes pork, not pig.
The answer "he likes pig" is not natural. It could be accepted, but "he likes pork" is more natural in English.
It Could work if it was identifying an animal he likes, but you'd have to add an 's' to pig: "He likes pigs."
But I agree, pig is not food.
So yá' át' ééh can mean hello, good and also to like, without any conjugation?
Yes. Basically it is, "with him, it is good". If you want to say "I like this" it is "shił yá'át'ééh", literally "with me it is good".
How is 'ł' pronounced?
It's a non vocalized l. It's like whispering an l.https://youtu.be/KxO7lCvOhlU
