While you can run an llm on an "old" laptop with an Nvidia GC it will likely be really slow. Like several minutes to much much longer slow. Huggingface.co is a good place to start and has a ton of different LLMs to choose from that range from small enough to run on your hardware to ones that won't.

As you are a teacher you know that research is going to be vital to your understanding and implementing this project. There is a plethora of information out there. There will not be a single person's answer that will work perfectly for your wants and your hardware.

When you have figured out your plan and then run into issues that's a good point to ask questions with more information about your situation.

I say this cause I just went through this. Not to be an ass.

Needed to add price gouging for parts into the bill as well

Outlawing Product Pairing

Proctor called the legislation “the best bill yet” because it goes a step further than other state’s right to repair laws by calling out and making illegal “product pairing,” in which onboard software makes it impossible to install parts that aren’t from the manufacturer.

Product pairing has become a favorite way for companies to make sure that products they sell are repaired only by them, and it’s not covered in any of the other state’s right to repair laws. Apple relies on product pairing extensively. iPhone owners, for instance, generally can’t replace any parts unless the phone can determine that the replacement is a genuine Apple replacement part. This led Apple, which has supported right to repair legislation in other states, to lobby against Oregon’s bill.

“We remain very concerned about the risk to consumers imposed by the broad parts-pairing restrictions in this bill,” Apple’s principal secure repair architect, John Perry, said in February at a legislative hearing.

“An iPhone contains its owner’s important personal data including financial, health, and location information, and this bill introduces the possibility that Apple would be required to allow unknown, non-secure third-party Face ID or Touch ID modules to unlock that personal information,” Apple said in a statement on March 4. “We will continue to support repair legislation, but strongly believe this bill does not offer the consumer protections Oregonians deserve.”

That’s all horse-hockey, of course, and basically a way for Apple to publicly support right to repair while denying it to its customers, as noted by iFixit,>

All you need to do is look at Portland Oregon. We decriminalized possession with Measure 110 and everyone rejoiced. Now most people are done with it. Used paraphernalia every where, homelessness everywhere. (Yeah I know housing prices is the major factor). Crime... Fuck me. The amount of people that have been "assisted" with their drug habits are dismal. In part due to government hindering the financial support. The major part is the lack of desire from users wanting to be saved. ( This is the alternative to jailing of persons) Decriminalization of possession of hard drugs was/is a major fail here. Just my anecdotal "research".
