You shouldn't have to do any of that. You should be able to just define the STEMMA sensor in the config.h and call Feather.measure() to get the data:
Config.h:

"{
'general':
{
'name':'Device',
'instance':1,
'interval':2000
},
'components':[
{
'name':'STEMMA',
'params':'default'
}
]
}"

Code:

#include <Loom.h>

// Include configuration
const char* json_config =
#include "config.h"
;

// In Tools menu, set:
// Internet > Disabled
// Sensors > Enabled
// Radios > Disabled
// Actuators > Disabled
// Max > Disabled

using namespace Loom;

Loom::Manager Feather{};

void setup()
{
Feather.begin_serial(true);
Feather.parse_config(json_config);
Feather.print_config();

LPrintln("\n ** Setup Complete ** ");

}

void loop()
{
Feather.measure();
Feather.package();
Feather.display_data();
Feather.pause();
}

Commented out the touchRead() and replaced with

uint16_t Adafruit_seesaw::touchRead(uint8_t pin) {
uint8_t buf[2];
uint8_t counter=0;
uint8_t p = pin;
uint16_t ret = 65535;

do {
  delay(1);
  this->read(SEESAW_TOUCH_BASE, SEESAW_TOUCH_CHANNEL_OFFSET + p, buf, 2,
5000); //increasing the length of the buffer time
ret = ((uint16_t)buf[0] << 8) | buf[1];

counter++;
} while ((ret == 65535) & (counter<3));
return ret;
}
