I just purchased a new iPhone 14 from Verizon and the sales person told me not to charge the 14 or my 13 Pro with an original iPhone charger. It should only be charged with the lightning fast charger, she stated the battery could be overcharged and damage if I charge with a regular iPhone charger.
is this true?

Using an original iPhone charger (typically 5W or 12W USB power adapter with a USB-A to Lightning cable) should not harm your iPhone 14 or 13 Pro’s battery. iPhones are designed to be compatible with a range of chargers and have built-in protections to prevent overcharging.
The main difference between the original charger and a Lightning fast charger (usually a higher-wattage USB-C power adapter with a USB-C to Lightning cable) is the speed at which they can charge your device. The fast charger, as the name suggests, can charge your iPhone more quickly.
However, do keep in mind that while fast charging can be more convenient, repeatedly fast charging your iPhone may cause the battery to degrade slightly faster over time compared to regular charging, due to increased heat produced during fast charging. This is a normal behavior for lithium-ion batteries.
That being said, it’s important to use only Apple-certified chargers for your device. Non-certified or counterfeit chargers could potentially damage your device or its battery.

By "original", I think the sales person meant an older 5 or 12 watt charger. It's not that they won't work, but the phone will charge very slowly.
For the iPhone 14 or 13, you want Apple's 20 watt charger.
The Verizon salesperson wanted to sell you another adapter. They have a quota of accessories they need to sell for every phone they sell. They are not above handing out some misinformation to encourage you to buy things.

Note that, if you have Optimized Charging enabled, you don't really need to worry about fast charging hurting your battery. The phone will stop charging at to let the phone cool when required.
No. That is not true. You can charge your iPhone 14 with any Apple approved charger and lightning cable (USB-C or USB-A) and the iPhone will handle the safe charging levels.
