You should be able to do something like:

$entity = 'catalog_product';
$code = 'status';
$attr = Mage::getResourceModel('catalog/eav_attribute')
    ->loadByCode($entity,$code);

if ($attr->getId()) {
    // atttribute exists
}

Magento 1.9 – Problem Saving Attribute with Modified Option Label

The exception is thrown in the method Mage_Eav_Model_Resource_Entity_Attribute::_saveOption by this code:

if (!isset($values[0])) {
    Mage::throwException(Mage::helper('eav')->__('Default option value is not defined'));
}

This means that $values[0] is not set

$values comes from this code in the same method foreach ($option['value'] as $optionId => $values) {

Apparently in your code $options['value'][Some numeric key here][0] is not set. See how the $options array looks like before passing it to the setOption method (last line in your code).

Magento 2 – How to Get Attribute Options Value of EAV Entity

you can add to the constructor of your class an instance of \Magento\Eav\Model\Config like this:

protected $eavConfig;
public function __construct(
    ...
    \Magento\Eav\Model\Config $eavConfig,
    ...
){
    ...
    $this->eavConfig = $eavConfig;
    ...
}

then you can use that in your class

$attribute = $this->eavConfig->getAttribute('catalog_product', 'attribute_code_here');
$options = $attribute->getSource()->getAllOptions();
