Nope. The RLGs themselves can deliver accuracy of 0.0035deg/hour, which over a 150km, <10 minute flight for GLSDB works out to <1.5m error and probably less than half that for GMLRS. It's probably be even cheaper than GPS too, and unjammable.
tan (0.0035deg/hr) x 150,000m x (10/60)hrs = 1.5m
A 2S7 is 10.5m long and 3.4m wide, 1.5m off centre is still a direct hit.
And that's just a crappy $1000 commercial system. Even more accurate systems were produced even 40 years ago, they were just prohibitively expensive back then.

^That equates to only 1.8m over a 14,000km, 30 minute flight!
These days, within the budget of a hypersonic missile, you could likely spec. a system with similar accuracy for $100k.
I don't believe RLGs are that accurate on aircraft. So the numbers work out in theory, and on the ground, but once you are in the air there's a lot more drift added to it. Even a slight deviation will mean a miss over large distances.
I am talking mainly for HIMARS and GLSDB at the moment. The ones for more expensive missiles and aircraft can justifiably be much more expensive, so they will have far better accuracy.

On that topic, it seems the Philippines' recently procured BrahMos SSMs will be getting targeting inputs from US platforms:
Philippines Builds First BrahMos Anti-Ship Missile Base Facing South China Sea - Naval News
The Philippines' first BrahMos missile base is being constructed in Western Luzon, orienting the missiles into the disputed South China Sea.
www.navalnews.com
The entire electronics suite of the BrahMos (including on-board & ground-based) was made fully MIL-STD to adhere to Indian military requirements so should present little, if any, difficultly in becoming part of the US/allied kill-chains, as long as the required downlinks for SATCOM/Link-16 are furnished by the operators for the Ground Stations.
They also successfully tested the block II seeker on the PrSM and sunk a ship with two in the recent SINKEX training exercise. PrSM being a 650km range ballistic missile with a 200lb warhead, measuring just 4m by 432mm. So now China appears to be surrounded by dozens of HIMARS, Typhon and Dark Eagle batteries based in Philippines, Taiwan and Japan, firing PrSMs (HIMARS Bty, 650km, 200lb warhead), Tomahawks and SM-6s (Typhon Bty, 500-1,600+km, 140-1000lb warheads respectively) and Dark Eagle aka LRHW (3,000km, 1,200lb warhead). All capable of sinking ships and targeted at the Taiwan Strait. There's also thousands upon thousands of drones, UAVs, USVs and UUVs.On that topic, it seems the Philippines' recently procured BrahMos SSMs will be getting targeting inputs from US platforms:
