As far as I understood you want to be able to access layerAttributes from outside the block, you can declare it outside then use it inside the const block and outside like this:

let layerAttributes = {}; //declared outside the block
    
    const addAttributes = (_element) => {
      let selectedElement = _element.layer;
      layerAttributes = { //accessed inside the block
        trait_type: _element.layer.trait,
        value: selectedElement.traitValue,
        ...(_element.layer.display_type !== undefined && {
          display_type: _element.layer.display_type,
        }),
      };
      console.log(layerAttributes);
      if (
        attributesList.some(
          (attr) => attr.trait_type === layerAttributes.trait_type
        )   
      )
        return;
      attributesList.push(layerAttributes);
    
    }; //end of block

    console.log(layerAttributes); //accessed outside the block

tell me if this is what you meant
