Morphology
The phrase is compositional: 'bedlam' denotes chaos and 'broke loose' (from 'break' + 'loose') denotes something escaping control or erupting, with 'all' functioning as an intensifier. Combined they predictably yield 'chaos erupted' — a common, cross-linguistically accessible concept — so a B1 learner who knows the constituent words should be able to infer the meaning.
Etymology
All bedlam broke loose comes from an old hospital called 'Bedlam' where patients were often loud and chaotic, and the image of broke loose is like something tied breaking free; so the phrase means 'sudden chaos'.
