She'll probably refuse to follow his advice — she dislikes him, after all.
Literal
She [topic-は] his [genitive-の] advice [as-どおりに] do thing [object-を] probably will-refuse, that-is him [subject-が] dislikes [because-ので].
A wordy, stilted refusal phrasing with 助言どおりに instead of the more natural 忠告に従う. The pattern ~どおり(に) ('exactly as, in accordance with') gives a sense of literal compliance: 'do exactly as the advice says.' たぶん ('probably') stacks with ~だろう ('likely') — together, doubly hedged ('probably will probably refuse'). というのは ~ので chains the post-statement explanation.
