There are things you can do to reduce the chance of hooking up with a large pike, like using smaller lures, smaller hooks on the lures or even different types of lures, but you can't avoid it completely. It's pretty difficult to target a certain size of Pike, so better be prepared for the big ones as well.
There are also things you can do to avoid getting spooled like following the fish along the shore, trying to get ahead of it and steering it into dead ends. Picking up the fishing spot matters a lot too. For example, at Old Burg, if you're casting West from the bridge at the pond (47:20 or thereabouts), there is very likely the fish will run West or North towards open water and take a lot of line. However, if you're fishing from the southern shore, for example casting East from 42:20, you're effectively casting in the same place, but it's not hard to steer the fish into the pond, where he can't spool you and you can safely tire him out.
However, even though catching larger fish is possible with lighter gear, you need to asses yourself if the time investment, gear wear and risk of losing materials is worth it over going for smaller, cheaper fish. In your case, is going for that 100 silver Pike order more efficient than a night of Bream fishing at OB? Or, idk, going for perch or catching Chubs at Winding if you're only into spin fishing? At least until you save some silver to buy better gear to target Pike.
In terms of gear, since I think this is what you're looking for, I would recommend a 15kg drag reel or thereabouts, with 300m of braid line to match it and a rod to support it.
There are some big pike at Old Burg, and in my experience, even a 10kg drag reel will struggle with the bigger ones, making you waste time to chase the fish around and tire him out, time you could spend catching smaller fish. Lately I've been using a Syberia Caliber HSV with 15.5kg drag and that one fights sub 10kg pikes reliably at Old Burg. You may have to chase the bigger ones for a bit, but overall it doesn't feel like I waste too much time. I haven't gotten any larger ones (trophy +), but those are rare and I'm confident it can deal with them, even if it takes a bit longer.
