You can catch a Shelmet on Azurine Island, then trade it in Spinel Town for a Karrablast, which will then immediatley evolve into Escalvier, which is great for Radomus's fight. Both because its steel/bug typing is good against Psychics, but also because its super slow and can take advantage of Trick Room. You can also grab a cubone in The Wasteland, and evolve it on Apophyll for Alolan Marowak, who's ghost typing is good for Radomus, and also has low Speed for Trick Room. What's more, it gets Stomping Tantrum at Level 43, letting you smash Radomus's field apart permanently.

I would suggest getting a male Meowstic with prankster (I know it is overused) for future fights as well. Having dual screens and access to great support moves like fake out will make future double battles much easier.
