にしたらFrom the point of view of

から見ると is used for objective judgment from a certain perspective, often based on observable facts, as in 専門家から見ると簡単だ (From an expert’s point of view, it’s easy). にしたら emphasizes a personal, subjective perspective, showing how it feels from someone’s position, as in 子供にしたら大問題だ (From a child’s standpoint, it’s a big problem).

にしたら conveys empathy with how someone might think or feel, as in 彼にしたら迷惑だっただろう (From his perspective, it must have been troublesome). という点から考えると is more analytical, focusing on one aspect logically, as in 経済の面という点から考えると重要だ (From the perspective of the economy, it’s important).

からすると・からすれば are objective, drawing conclusions from evidence, as in 態度からすると本気だ (Judging from his attitude, he’s serious). にしたら highlights a subjective, inner viewpoint, as in 親にしたら心配だろう (From a parent’s perspective, they must be worried).

からして judges from a single strong piece of evidence, often critically, as in 言葉遣いからして失礼だ (Even just from his wording, it’s rude). にしたら centers on a person’s standpoint, neutral or sympathetic, as in 子供にしたら楽しい経験だ (From a child’s perspective, it’s a fun experience).

にしたら and 点 are similar in that both can express the idea of a standpoint, but differ in nuance. にしたら expresses an opinion from a personal or empathetic point of view, e.g. 子どもにしたら大事件だ ('For a child, it's a big deal.'). In contrast, 点 will typically highlight a reference point for objective analysis, e.g. 安全性の点では問題がある ('There's a problem from a safety standpoint.').

から言うと and にしたら both express perspective, but differ in nuance. から言うと gives an opinion or evaluation from a stated viewpoint, e.g. 医者から言うとこれは異常だ ('From a doctor's perspective, this is abnormal'). にしたら puts the speaker in someone else's position to make a subjective judgment, e.g. 子供にしたら怖かっただろう ('It must have been scary from the child's perspective').

に取って (usually written in kana as にとって) indicates a perspective or viewpoint, e.g. 社会にとって必要な制度だ ('It's a necessary system for society'). にしたら also means 'for (A)', but often implies a more subjective or emotional stance, e.g. 親にしたら心配だろう ('For a parent, it must be worrying').
