I am confused what you mean by that.
Are you talking about the logic parts in the [Digital] section of the library?? They all have actual models already.? What's missing are the parameters that MAY need to be set, to get realistic performance.
I am not aware of logic parts in the LTspice library that are graphical symbols only.
Some analog parts, e.g., MESFETs, SCRs, IGBTs, valves/tubes, and varistors, are symbols only and you must provide the model.
