She loved to throw money around.
Literal
She [topic-は] money [object-を] scatter [nominalizer-の] [subject-が] liked was.
ばらまく is a vivid verb — 'to scatter, sprinkle, throw around indiscriminately.' Originally about scattering grain, salt, or seeds, it extends figuratively to money, leaflets, or anything one is distributing widely without much care. The frame Vのが好きだ ('like to do X') is the standard structure for verbal preferences — の nominalizes the verb, が marks the resulting noun-phrase as the subject of 好き. ~だった makes the whole liking past-tense.
