I am a new 2007 is350 sport trim owner and I was looking at the f sport lowering springs on the Lexus parts website, I was wondering if that would make a difference or because I already have the sport trim it will not change the ride height because of the sport trim springs original to the car

About 3/4" but F-Sport factory equipment are linear vs progressive. Meaning you need to match dampers.

So if I replaced the stock springs with the f sport springs would it lower the car, and would I need to buy the suspension struts as well? It says on the part website that I don’t

You can replace the stock springs with the F-Sport springs and still use the stock shocks.

yeah, it's pretty much impossible to ever correctly match the shocks with the spring rate of progressive springs, so the shocks would probably wear out quicker. The linear springs are matched up with the shocks.
