You need to remove the square brackets around terms and top_hits

$params2 = [
        'index' => 'index',
        'type'  => "items",
        'body' => [
            'aggs'  => [
                "types" => [
                    "filter" => [
                        "bool" => [
                            "should" => [
                                ["term" => ["type_id" => 1]],
                                ["term" => ["type_id" => 2]]

                            ]
                        ]
                    ],
                    "aggs" => [
                        "types" =>[
                            "terms" => ["field" => "type_id","size" => 4],
                            "aggs" =>[
                                "top" => [
                                    "top_hits" => ["size" => 2]
                                ]
                            ]
                        ]
                    ]
                ]
            ],
        ]
    ];
