I encountered the similar issue before, I would use the following approach for achieving my purpose, you could refer to it:

local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=brucchstorage;AccountKey=",
    "AzureWebJobsDashboard": "DefaultEndpointsProtocol=https;AccountName=brucchstorage;AccountKey=",
    "sqldb-connectionstring": "Data Source=.\\sqlexpress;Initial Catalog=DefaultConnection;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"
  },
  "ConnectionStrings": {
    "Bruce_SQLConnectionString": "Data Source=.\\sqlexpress;Initial Catalog=DefaultConnection;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"
  }
} 

For retrieving the connection string:

var connString = ConfigurationManager.AppSettings["sqldb-connectionstring"];
//or var connString = ConfigurationManager.ConnectionStrings["Bruce_SQLConnectionString"].ConnectionString;
using (var dbContext = new BruceDbContext(connString))
{
    //TODO:
}

Or you could init your no-argument constructor for your DbContext as follows:

public class BruceDbContext:DbContext
{
    public BruceDbContext()
        : base("Bruce_SQLConnectionString")
    {
    }

    public BruceDbContext(string connectionString) : base(connectionString)
    {
    }
}

Then, you could create the instance for your DbContext as follows:

using (var dbContext = new BruceDbContext(connString))
{
    //TODO:
}

Moreover, you could refer to Local settings file for Azure Functions.
