Example code:

<?php declare(strict_types = 1);

class Dummy01
{
    public int $type;

    public function __construct(string $type)
    {
        $this->type = $type;
    }
}

Here, assigning a string to an integer is not detected by PHP Tools. PHPStan does detect:

Property Dummy01::$type (int) does not accept string.

Suggestion

Please make PHP Tools aware of assigning wrong types.
