I was wondering, how LTspice models for ICs are made? |

Hum... It is a large subject. You know the Berkely Spice existing elements? It is generally about an individual component, or, if you prefer, an MCU or something really complex is probably out of scope, in general (I suspect that TI, AnalogDevices, Intel, etc. as example, use their own internal tools, and not a standard Spice version). With the standard version, you can use basic elements to describe the behavior of your "sub circuit", but there is always some tweaking if you really want to be close to your chip, unless the model is already developed by the manufacturer. As example, for thyristors, you can check many examples such as this one by Littlefuse. You can also take a look at a model of the TL431, by TI, (answer #7, the model is not by them) to see what kind of work is involved. BUT as you can see, that is clearly OUT OF SCOPE of a standard question-answer for a discussion forum, imvho. |

And if you are still wishing to include an external Spice model (already made), you can check this YouTube great video. |
