'I'm going to see your dad today. Career counseling.' 'No thanks, I don't need that kind of thing.'
Literal
'Today dad [to-に] meet-[purposive-に] go. Career-counseling [copula-だ].' 'Fine-[emphatic-よ], that-sort-of-thing [emphatic-の].'
進路相談 is a specifically Japanese educational/institutional concept — formalized career-path counseling where a student's grades, aptitudes, and parents are discussed together to decide on a high school or university track. Here it's used casually in a family context. いいですよ in a refusal context means 'no thanks / I'm fine without it,' opposite its 'that's fine / permission-granted' use — a classic learner pitfall. The trailing そんなの with の adds emphatic dismissal, 'stuff like that.'
